Speciation, mobility, and risks of heavy metals in sediment and water of a freshwater Lake in Fujian Province, China

ABSTRACT This study investigated the level of dissolved heavy metals in the water of Longhu Lake and focused on the speciation, mobility, and risks of heavy metals (Cr, Mn, Ni, Cu, Zn, As, Cd, and Pb) in sediment. The levels of heavy metals in the water were found to be below the thresholds set by the Chinese safe drinking water standard. The highest average percentages of Cr, Ni, Zn, and As were bound with residual fractions, while Pb and Cu were bound with reducible fractions. Additionally, the highest percentage of Cd and Mn was bound to the acid-soluble fraction in the sediment. These findings suggest that Cd, Mn, Pb, and Cu likely originated from anthropogenic sources in the lake. There was a strong correlation between total organic carbon (TOC) and metal fractions in the sediment, indicating that TOC may play a role in transporting heavy metal fractions. Risk assessment code values for Cd and Mn indicated higher risks and mobility, while Ni, Cu, and Zn showed medium risks and mobility for aquatic biota. To mitigate heavy metal contamination, it is recommended to improve monitoring and regulation of urban runoff and inlet areas.

Chemical Speciation, Leaching Behavior, and Environmental Risk Assessment of Trace Elements in the Bottom Ash from Biomass Power Plant.

Biomass combustion for power generation stands as a pivotal method in energy utilization, offering a promising approach for renewable energy utilization. However, the substantial volume of slag produced by biomass burning plants poses environmental challenges, impeding sustainable energy practices. This article systematically studies the characteristics of ash generated from typical biomass direct combustion power plant ash and analyzes the chemical composition, trace element content characteristics, leaching characteristics, and chemical forms of biomass bottom ash. Furthermore, it assesses the environmental ecology and bioavailability of trace elements in bottom ash using the ecological risk assessment method and RAC method. The results demonstrate that the biomass bottom ash contains plant nutrients, such as K, Ca, Mg, and P, while the content of harmful trace elements is lower than the relevant Chinese standards. In dissolution experiments, the leaching rate of nearly all elements remains exceptionally low, primarily due to the distribution of trace elements within the lattice structure of stable minerals. Trace elements predominantly exist in the residual phase, Cu and Zn primarily found in organic compounds and sulfide bound states, while other elements mostly exist in the form of iron manganese oxide bound states. Ecological risk assessment indicates a significant risk level for Cd, contrasting with the slight risk associated with other elements. RAC results indicated no ecological risk of all of the trace elements. Consequently, the utilization of bottom ash in agricultural and forestry soils is deemed to be viable. These findings serve as a crucial foundation for biomass bottom ash resource utilization and underpin the sustainable utilization of biomass energy.

A novel tryptanthrin-based "on-off-on" probe for sequential sensing Cu2+/S2- in water samples.

Copper ions (Cu2+) and sulfide (S2-) play essential roles in many physiologies and pathologic processes. Herein, a new "on-off-on" tryptanthrin-based probe TR-1 (TR-1) has been designed and synthesized inafacileandeconomicalway. TR-1 exhibited highly selective and sensitive response to Cu2+ without any interference over 14 competitive metal ions and the detection limit downs to 24nM, which is far below the Chinese standard of fishery water quality (157nM). The 'in situ' prepared complex TR-1 + Cu2+ could also be applied to detect S2- with the detection limit of 62nM. Further, TR-1 was potentially applied for the analysis of copper ions in water samples.

A Qualitative Case Study of Teachers’ Perceptions on a Two-model System; Adhering to Chinese and International Baccalaureate Mandated Standards

National curriculum standards for different countries mean some International Baccalaureate (IB) schools must often balance IB and national standards. Literature on how schools find this balance is limited. Using a qualitative case study design, we examined the perspectives of teachers of English in a Chinese IB school that recently employed a two-model system to address government mandates while still adhering to IB policies. A two-model system occurs when the two curricula are taught separately rather than in an integrated way. Our findings describe teachers’ understanding of a two-model system, identify challenges for teachers in its implementation, and suggest improvements. Results are confined to a single context of an English department in China and cannot therefore be generalized. Our findings reveal an overall theme of separateness identifying structural and conceptual factors affecting the relationship between the two models. The article discusses new ideas for curriculum structures that might inform school decisions for similar IB schools and schools with integrated curricula.

科研人员科学数据元数据功能需求探索

In the context of data sharing and the advancement of open science, this study analyzes the functional requirements of scientific data metadata based on the requirements of scientific researchers for data resources, so as to provide valuable insights for the construction and enhancement of Chinese scientific data metadata standards. We gathered the functional requirements of scientific data metadata from 30 researchers in the research process during semi-structured interviews, and constructed a model for the functional requirements of scientific data metadata based on the information behavior theory. The findings show that the functional requirements of scientific data metadata are significantly affected by individual value perceptions and discipline differences, which can be reflected in the process of scientific data exchange and sharing. This paper provides insights and suggestions for the construction of scientific data metadata from three aspects: demands of researchers, information behavior process and data life cycle theory.

Quantitative Prediction of Surface Hardness in Cr12MoV Steel and S136 Steel with Two Magnetic Barkhausen Noise Feature Extraction Methods.

The correlation between magnetic Barkhausen noise (MBN) features and the surface hardness of two types of die steels (Cr12MoV steel and S136 steel in Chinese standards) was investigated in this study. Back-propagation neural network (BP-NN) models were established with MBN magnetic features extracted by different methods as the input nodes to realize the quantitative prediction of surface hardness. The accuracy of the BP-NN model largely depended on the quality of the input features. In the extraction process of magnetic features, simplifying parameter settings and reducing manual intervention could significantly improve the stability of magnetic features. In this study, we proposed a method similar to the magnetic Barkhausen noise hysteresis loop (MBNHL) and extracted features. Compared with traditional MBN feature extraction methods, this method simplifies the steps of parameter setting in the feature extraction process and improves the stability of the features. Finally, a BP-NN model of surface hardness was established and compared with the traditional MBN feature extraction methods. The proposed MBNHL method achieved the advantages of simple parameter setting, less manual intervention, and stability of the extracted parameters at the cost of small accuracy reduction.

A Comprehensive Review on Water Permeability Testing and Sealing Techniques in Concrete Construction

This paper introduces the water permeability test process of concrete in China, Europe and the United States, and explains the sealing method of specimens in the water permeability test of concrete according to the Chinese standard, so that the construction inspection industry personnel can choose according to the actual situation of the project and the evaluation needs.

A novel, low-cost, and efficient separation strategy based on S-doped C3N4 for the analysis of PCDD/Fs and dioxin-like PCBs

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) are widespread and highly toxic persistent organic pollutants with similar chemical structure. The popular process for the separation of PCDD/Fs and dl-PCBs in one sample often relies on imported and expensive activated carbon, giving rise to an urgent need of inexpensive and efficient separation method. Herein, a novel, simple, and low-cost separation strategy based on sulfur-doped carbon nitride (S-C3N4) is reported. The S-C3N4 material was synthesized through simple thermal annealing with precursor of thiocyanuric acid. After recovery experiments, the optimal addition ratio of S-C3N4 was determined to be 40% mixed with silica gel. The recoveries for PCDD/Fs and dl-PCBs congeners are 32% - 105% and 60% - 70% respectively, which not only meets USEPA and Chinese standards but also shows comparable performance to activated carbon. Moreover, the proposed S-C3N4 strategy exhibits excellent performance for the analysis of PCDD/Fs and dl-PCBs in real complex samples (sediment and fish liver) in terms of detected concentrations and toxic equivalents. Overall, this study puts forward a new and low-cost avenue for the separation of PCDD/Fs and dl-PCBs, which is of remarkable meaning for motivating the development of detection techniques and domestic equipment for dioxins and other pollutants in the environment.

Assessment of occupants’ adaptive capacity: a case study in northern Guizhou of China

The thermal comfort of rural residents is a major issue related to people’s livelihood. Due to differences in climatic factors (e.g. local climate) and non-climatic factors (such as building structures, economic and social–cultural levels, living habits and availability of environmental control) between rural and urban areas, participants have different thermal requirements for a given thermal environment. This difference means that thermal comfort standards that consider only urban conditions may not be applicable to rural situations. Therefore, a thermal comfort field study was conducted on the thermal comfort of traditional residential houses with natural ventilation located in rural areas of northern Guizhou, China. This study aims to understand the indoor thermal conditions and perceptions of occupants in rural areas, with a total of 513 subjects that participated in a questionnaire survey. Most survey respondents accept the thermal environment in which they reside, even if the indoor temperature is not within the recommended thermal comfort range specified by international standards such as Ashrae 55. The adaptive predicted mean vote is established using the least-squares method. The adaptive coefficient λ representing the adaptive capacity is twice the recommended coefficient of the Chinese standard, GB/T 50785-2012. This confirms that rural residents have a stronger adaptability to cold conditions in winter. The findings are beneficial for improving thermal comfort and carbon dioxide emission reduction for traditional residential houses in rural areas of northern Guizhou, China.

A novel biochar-augmented enzymatic process for conversion of food waste to biofertilizers: Planting trial with leafy vegetable

The present study developed a novel biochar-augmented enzymatic approach for fast conversion of food waste to solid and liquid biofertilizers. By augmented with 10 % of biochar and mediated with 5 % of food waste-derived hydrolytic enzymes mixture (i.e. fungal mash), 100 kg of food waste could be converted into 22.3 kg of solid biofertilizer with a water content of 30 % and 55.0 kg of liquid biofertilizer, which fulfilled Chinese national standards for solid and liquid organic biofertilizers, respectively. Field plantation results showed that the Pak Choi grown on food waste-derived biofertilizers was comparable with that on commercial ones, in terms of the vegetable productivity and nutrient contents. It was further revealed that the application of food waste-derived biofertilizers did not change soil chemical properties but enriched microbial diversity. This study clearly indicated that the biochar-augmented enzymatic approach for food waste conversion to biofertilizers was technically feasible and economically viable towards circular agriculture economy.

Development of the assessment standards of the International Classification of Functioning, Disability, and Health (ICF) Geriatric Core Set through a modified Delphi method

BackgroundThere is currently a lack of functional assessment tools based on the International Classification of Functioning, Disability, and Health (ICF) theoretical framework that are specific for older adults.ObjectiveThe aim of the present study was to develop Chinese assessment standards of the ICF Geriatric Core Set for functional evaluation of older adults.MethodsA two-stage study process was conducted to develop the assessment standards of the ICF Geriatric Core Set: establishment of candidate assessment standards, and a modified Delphi consensus process including a pilot survey and two-round formal expert survey. Thirty participants in the field of ICF and geriatric rehabilitation were recruited. The suitability of the assessment standards in the questionnaires was rated using a Likert 5-level scoring method. The arithmetic mean, the full mark ratio and the coefficient of variation (CV) were used as screening indicators for the assessment standards, and modification was made for several standards, in line with the Delphi results and the expert panel discussion.ResultsThirty-three candidate assessment standards belonging to 17 categories were generated. A total of 26 and 24 experts in the field of ICF and geriatric rehabilitation participated in the two-round survey, respectively. Five standards belonging to four categories entered into the second-round survey directly, five standards belonged to five categories entered with minor modification, and nine standards belonging to seven categories were redesigned based on the literature and discussion of the expert panel. In the second-round survey,15 assessment standards belonging to 15 categories met the screening requirements and four assessment standards belonged to the two remaining categories that needed a criterion and which the expert panel discussed for the final decision.ConclusionsUsing the modified Delphi method, the assessment standards of the ICF Geriatric Core Set have been developed.Future work should focus on the reliability and validity of the the assessment standards and their application to the health management of older adults.

A Comparative Study on the Difference of Blood Pressure Criteria and the Difference in Blood Pressure Measurement Among Children and Adolescents in China, the United States, and Europe

Abstract OBJECTIVE To compare the difference of blood pressure criteria and the difference in blood pressure measurement among children and adolescents. METHODS The latest blood pressure criteria for children and adolescents in China, the normal blood pressure standard the United States, and Europe have been used to calculate blood pressure differences for the same age, gender, and height. Based on 3 blood pressure measurements of 45,314 Chinese and 15,279 American children and adolescents, the differences in blood pressure measurements were calculated through repeated measurement analysis of variance and compared with criteria differences. RESULTS More than 60% of the difference in blood pressure standard is distributed between −3 and 3 mm Hg. But the difference between Chinese standards and American standards can be 5–10 mm Hg in children aged 13. The difference between Chinese standards and European standards can be 6–9 mm Hg at the age of 16. The analysis of repeated blood pressure data shows that the maximum difference in systolic blood pressure measurement for Chinese boys and girls is 3.7 and 4.1 mm Hg, respectively, and the maximum difference in diastolic blood pressure measurement is 2.0 and 2.1 mm Hg. The difference between the 3 measurements of boys and girls in the United States is nearly 1 mm Hg. CONCLUSIONS The difference between blood pressure standards is smaller than the measurement difference, and accurate measurement and repeated measurement of blood pressure may be more important for evaluating blood pressure status than the selection of blood pressure standards.

Cardiorespiratory effects of indoor ozone exposure during sleep and the influencing factors: A prospective study among adults in China

Ambient ozone (O3) is recognized as a significant air pollutant with implications for cardiorespiratory health, yet the effects of indoor O3 exposure have received less consideration. Furthermore, while sleep occupies one-third of life, research on the health consequences of O3 exposure during this crucial period is scarce. This study aimed to investigate associations of indoor O3 during sleep with cardiorespiratory function and potential predisposing factors. A prospective study among 81 adults was conducted in Beijing, China. Repeated measurements of cardiorespiratory indices reflecting lung function, airway inflammation, cardiac autonomic function, blood pressure, systemic inflammation, platelet and glucose were performed on each subject. Real-time concentrations of indoor O3 during sleep were monitored. Associations of O3 with cardiorespiratory indices were evaluated using linear mixed-effect model. Effect modification by baseline lifestyles (diet, physical activity, sleep-related factors) and psychological status (stress and depression) were investigated through interaction analysis. The average indoor O3 concentration during sleep was 20.3 μg/m3, which was well below current Chinese indoor air quality standard of 160 μg/m3. O3 was associated with most respiratory indicators of decreased airway function except airway inflammation; whereas the cardiovascular effects were only manifested in autonomic dysfunction and not in others. An interquartile range increases in O3 at 6-h average was associated with changes of −3.60 % (95 % CI: −6.19 %, −0.93 %) and −9.60 % (95 % CI: −14.53 %, −4.39 %) in FVC and FEF25–75, respectively. Further, stronger effects were noted among participants with specific dietary patterns, poorer sleep and higher level of depression. This study provides the first general population-based evidence that low-level exposure to indoor O3 during sleep has greater effects on the respiratory system than on the cardiovascular system. Our findings identify the respiratory system as an important target for indoor O3 exposure, and particularly highlight the need for greater awareness of indoor air quality, especially during sleep.

Study on the test accuracy of the high-air-volume purifier under different test chamber volumes

Due to the increasing local purification demand of public spaces during production processes, high-air-volume purifiers (HAVPs) with flow rates >800 m3/h have been increasingly applied in commercial and industrial spaces. Compared with clean air standards in the United States, Europe and other countries, relevant HAVP detection guidelines have not been standardized in most countries, and only Chinese and South Korean standards consider scaling HAVP test chambers. There remains a lack of theoretical and experimental HAVP detection studies. In this study, the airtight test chamber decay method was used, and the chamber size was increased by a ratio of 1:2:3 based on the original volume (30 m3). The effect of the test chamber volume on the HAVP accuracy was evaluated considering the amount of valid data, pollutant uniformity, and air cleaner position. Based on the results, the clean air delivery rate (CADR) deviation varied between 1.4% and 35.7% under the effect of the test chamber volume. The test accuracy was higher for the 60 m3 test chamber, which is more suitable for HAVP testing. A new index based on the CADR–test chamber volume relationship was proposed, revealing that the air cleaner performance can be accurately measured when the equivalent clean air volume ventilation rate varies between 9 and 22 L/h. The upper HAVP detection limit should be considered in standard supplementation. The HAVP flow rate classification in Chinese standards should be refined. The results provide a reference for rapid selection of the appropriate test chamber volume for air cleaners with different flow rates, which facilitates HAVP application in industrial and commercial spaces.

Scientific connotation of temperature control in processing of Chinese medicinal materials based on theory of quality evaluation through morphological identification

Processing of Chinese medicinal materials is an important part in the Chinese medicine heritage, and the temperature control in the processing has a direct impact on the quality and efficacy of traditional Chinese medicines. However, the processing of Chinese medicinal materials has the problems of subjective temperature judgement, determination of the end point based on experience, unclear processing mechanism, unstable quality of products, and inconsistent processing standards. The temperature control in the processing is reflected in the appearance and internal quality of Chinese medicinal materials. The theory of quality evaluation through morphological identification is developed based on the comprehensive evaluation of the shape, color, taste, and components, which is associated with the temperature control in the processing. To solve the problems above, this paper puts forward the following solutions. The first is literature mining. By review of the ancient medical works and pharmaceutical experience, the temperature control in processing and the evolution of processing methods can be revealed. Second, according to the ancient method, the processing principle can be explored, on the basis of which the processing technology can be innovated. Third, the standard operating procedure(SOP) should be established to quantify the fire temperature, providing a theoretical basis for the formulation of Chinese medicinal material processing standards. Moreover, it provides a basis for improving the quality of processed products and increasing the safety and effectiveness of traditional Chinese medicines.

Study on Improved Large Span Propping System for Reinforced Concrete Composite Slabs with Lattice Girders

To further improve the installation efficiency of commonly used reinforced concrete composite slabs with lattice girders in China, an Improved Large Span Propping System is proposed. This article investigates the mechanical properties of the new propping system through in-situ monitoring. The monitoring results show that the displacement and stress of the prefabricated layer can meet the requirements of current Chinese standards, which indicates the feasibility of the new support system. Compared with the original Large Span Propping System, the new propping system can further utilize the bending stiffness of the prefabricated layer and reduce the installation amount of the lower propping frame.

Effect of Consultation Number on the Assessment and Treatment of Polycystic Ovary Syndrome.

The basic medical education stage is not enough to support physicians to fully diagnose and evaluate polycystic ovary syndrome (PCOS). The study aims to discover the difference in treatment choice between participants with different annual consultation number of PCOS, to promote lifelong learning, and drive balanced development within healthcare. This is a multicenter cross-sectional survey. Participants' basic information, knowledge of PCOS and treatment options were collected online. According to the annual consultation number of patients with PCOS, physicians were divided into three groups: 0-50 people/yr, 50-200 people/yr, and >200 people/yr, and the results were derived from χ2 test, Fisher exact test, and multivariate logistic regression analysis. The study analyzed 1689 questionnaires, and 1206 physicians (71.4%) received less than 50 women per year, 388 physicians (30.0%) with an annual number of 50-200 women, and 95 physicians (5.6%) with patient turnover for more than 200 people. Reproductive endocrinologists generally have higher access to the clinic. As the number of visits increases, more and more physicians would perceive patients as more likely to have abnormal blood glucose and heavy weight. Physicians with large numbers of consultations are more likely to use Asian or Chinese standards to assess obesity. The multivariate analysis involved variables such as age, hospital level, specialty, and patient turnover annually, and more young doctors actively assessed lipid profile (odds ratio (OR) 1.56, 95% confidence interval (CI) (1.16, 2.16)), and primary hospitals (OR 0.65 CI (0.44, 0.89)) chose OGTT for blood glucose assessment less than tertiary hospitals. Physicians in secondary hospitals are more aggressive in evaluating androgens. Our survey found differences in endocrine assessment, metabolic screening, and treatment in PCOS women in terms of the number of obstetrician-gynecologists who received different patient consultation numbers. The importance of continuing education for physicians is emphasized, to promote lifelong learning.

In-hospital and mid-term follow-up of low-density lipoprotein cholesterol and target-goal attainment among patients with acute cerebral infarction: a retrospective study

ObjectiveTo investigate the baseline and six-month follow-up data of the main lipid indices as well as low-density lipoprotein cholesterol (LDL-C) target goal attainment in accordance with the current guidelines among patients with acute cerebral infarction (ACI).MethodsOne thousand ninety-nine patients were consecutively enrolled from January 2021 to December 2022 and divided into ACI, old cerebral infarction (OCI), and control groups. General data [sex, age, body mass index (BMI), medications, smoking status, disease history, etc.], baseline data, and six-month follow-up main laboratory data were collected and analyzed. ACI patients were grouped into dyslipidemia and normal groups according to the lipid management guidelines of the European, American, and Chinese populations. Statistical methods were used to screen for possible predictors of dyslipidemia.ResultsPatients with ACI or OCI had higher total cholesterol (TC) and LDL-C levels than did the control group (all P < 0.05). According to European (94.7%, 89.0% and 13.4%, P < 0.01), American (94.7% vs. 67.7% vs. 45.9%, P < 0.001) and Chinese (85.1% vs. 59.1% vs. 18.6%, P < 0.001) standards, the proportion of dyslipidemia in the ACI group was greater than that in the OCI and control groups. According to European and American standards, increases in BMI and the estimated glomerular filtration rate (eGFR) are predictors of dyslipidemia in ACI patients. According to Chinese standards, increases in BMI, glycated hemoglobin (HbA1c) levels, and eGFRs are independent predictors of dyslipidemia in ACI patients. The 6-month follow-up of the main lipid levels revealed that among the ACI group, TC, LDL-C and triglyceride(TG) levels (4.86 vs. 3.79, P < 0.001; 2.98 vs. 2.01, P < 0.001; 1.46 vs. 1.20, P < 0.001) and the proportion of dyslipidemia decreased significantly in accordance with European/American and Chinese standards (86.8% vs. 64.6%, P = 0.015; 97.2% vs. 84.7%, P = 0.012).ConclusionThese results revealed that lipid management is still not optimal for patients with ACI. More attention should be given to ACI patients with elevated BMI, eGFR, and HbA1c values, which could lead to more individualized lipid management. Although the main lipid levels decreased significantly 6 months after discharge with lipid-lowering therapy, there is still a long way to go to enable more ACI patients to meet the guideline-recommended LDL-C target goal.

TCMSSD: A comprehensive database focused on syndrome standardization

BackgroudQuantitative and standardized research on syndrome differentiation has always been at the forefront of modernizing Traditional Chinese Medicine (TCM) theory. However, the majority of existing databases primarily concentrate on the network pharmacology of herbal prescriptions, and there are limited databases specifically dedicated to TCM syndrome differentiation. PurposeIn response to this gap, we have developed the Traditional Chinese Medical Syndrome Standardization Database (TCMSSD, http://tcmssd.ratcm.cn). MethodsTCMSSD is a comprehensive database that gathers data from various sources, including TCM literature such as TCM Syndrome Studies (Zhong Yi Zheng Hou Xue) and TCM Internal Medicine (Zhong Yi Nei Ke Xue) and various public databases such as TCMID and ETCM. In our study, we employ a deep learning approach to construct the knowledge graph and utilize the BM25 algorithm for syndrome prediction. ResultsThe TCMSSD integrates the essence of TCM with the modern medical system, providing a comprehensive collection of information related to TCM. It includes 624 syndromes, 133,518 prescriptions, 8,073 diseases (including 1,843 TCM-specific diseases), 8,259 Chinese herbal medicines, 43,413 ingredients, 17,602 targets, and 8,182 drugs. By analyzing input data and comparing it with the patterns and characteristics recorded in the database, the syndrome prediction tool generates predictions based on established correlations and patterns. ConclusionThe TCMSSD fills the gap in existing databases by providing a comprehensive resource for quantitative and standardized research on TCM syndrome differentiation and laid the foundation for research on the biological basis of syndromes.

Seismic performance of a frame‐supported shear wall over‐track building through shaking table test

SummaryThis research deals with a frame‐supported shear wall for urban over‐track building of vehicle depot in Chisha, Guangzhou, China, which is characterized by its remarkable height of 160.8 m. Technical issues are commonly encountered in these kinds of buildings due to discontinuous vertical structural rigidity, large podium, and structural transition. These challenges significantly impact the engineering process, especially when the rigidity difference between transfer story exceeding the threefold, as well as the building height exceeds limit as in code. In this paper, a shaking table test was developed based on a 1:10 scaled model of the structure. Using similarity theory, the dynamic similarity relationship was established for the design of the model. Subsequently, the experimental model was constructed with the configuration of critical parameters such as mass design, sensor placement, and seismic test conditions. This was followed by in‐depth analysis, recording component failures and investigating key aspects such as dynamic characteristics, that is, acceleration and displacement responses and shear force distribution under different earthquake intensities. A theoretical seismic response of the prototype structure was derived from the test results. The shaking table tests confirmed that the structure met the stringent seismic design requirements as prescribed in the Chinese standards, with no damage under minor earthquakes, repairability under moderate earthquakes, and collapse prevention under rare earthquakes. The results of the study provide valuable insights along with improvement measures for the design and development of similar urban over‐track buildings, potentially contributing to more efficient land use in urban China.
