Research on Underground Track Tracking of a New Type Shaft Boring Machine

A trajectory tracking control scheme is proposed in this paper to achieve unmanned underground construction of a new type of shaft boring machine. The body motion model is constructed, and the control relationship between the driving system and the body motion is deduced. MATLAB and Simulink simulate the joint of the track tracking process in the new shaft boring machine. The actual effect of the track tracking control scheme is validated by the track tracking field test of the new shaft boring machine. The results show that the new shaft boring machine can complete various complex track tracking tasks, with the maximum position error being less than 0.005 m. The running track and excavation areas of the boring machine are observed along with the track tracking field test of the new shaft boring machine, demonstrating that the track tracking control scheme makes the new shaft boring machine realize unmanned construction and verifies the co-simulation accuracy. The PID (proportional–integral–derivative control) algorithm can complete complex trajectory tracking tasks and promote the development of unmanned construction technology.

Analisis Standard Kapasitas Pullplate pada Kayu Sengon Menggunakan Metode Uji Tarik di PT XXX

Unloading is the process of removing the unit from the container, in the process it requires a tool, namely a pulplate, in the process there is often a failure of the unloading process that occurs this is due to the pulplate detaching from the wood so that the unit cannot be removed from the container under normal conditions. This study aims to analyze the strength of the screw patern in the pulplate connection with sengon wood using the tensile test method. The connection between pulplate and wood is an important aspect in wood construction, especially in structural applications. The tensile test method was used to evaluate the joint strength and performance of the patern screw under various tensile load conditions. This study was conducted by taking samples of pulplate and sengon wood connections that have been installed using a patern screw, and then subjected to a tensile force until they reach the point of failure. The analysis results will provide a better understanding of the strength of the connection between pulplate and sengon wood, as well as make it possible to optimize the screw patern design and improve the structural reliability of the connection. This research is expected to make an important contribution to the development of efficient and sustainable wood construction technology. The results showed that the new design was able to support a average load 1150.04 kg, compared to the old design which could only accommodate a average load 1115.39 kg. So we suggest changing the pullplate model currently in use and making new rules regarding pullplate installation which is expected to increase the reliability of the pullplate work function at PT XXX.

Comparative analysis of Environmental Impact of Each Building Material using Life Cycle assessment(LCA)_Focusing on Types of Construction Wood and Concrete

Objectives:The construction sector is a very important sector in achieving carbon neutrality. In modern society, construction has grown rapidly, and basic materials such as cement and concrete have contributed greatly to the development of construction. These materials emit a large amount of global warming substances during the raw material extraction and production process, causing serious environmental pollution. In order to establish a carbon reduction strategy to slow down global warming, we compared the environmental impacts of each building material and showed the current situation.Methods:The LCI DB for the construction materials used in the two-story wooden house (Building area 128.67m2, total floor area 235.73m2) located in the National Institute of Forest Science was extracted. Then, the data for LCA was processed and performed through the life cycle assessment methodology for the resources consumed from raw material collection, material production, and transportation stages. Then, based on the environmental performance labeling impact assessment method, a study was conducted on the environmental impact categories of the actual construction materials used and comparisons with other construction materials.Results and Discussion:When analyzing the environmental impact of concrete [25-21-120] and construction wood used in wooden house, the environmental impact was found to be 98.79% higher on average in the pre-manufacturing stage than in the manufacturing stage, and construction wood was confirmed to have a reduction effect of 62.21 kg CO2-eq per 1 m3 compared to concrete. Through the scenario, there was a carbon reduction effect of up to 36% when the entire area was replaced with wood. In addition, the environmental impact by major construction material was quantitatively quantified.Conclusion:When building a wooden house, reducing the amount of concrete equivalent to the amount of wood is expected to have a greenhouse gas reduction effect, so it is time to activate construction wood from the production process to the post-production stage to replace concrete. In addition, follow-up research on the development of construction technology with low environmental impact during construction should be continued. This study is expected to be used as a useful indicator for R&D and policies in the construction field in the future, as it quantitatively quantified the amount of CO2 reduction per m3 when replacing concrete with construction wood and numerically compared and analyzed six major environmental impact categories by major construction materials.

Experimental studies of the «Sila» node

This article addresses the issues of wood shrinkage and the associated deformations that lead to cracks in log structures. Special attention is given to deformations in houses made of rounded logs. These deformations occur due to uneven changes in the geometry of the wood during drying, leading to high stresses and longitudinal cracks. Various methods are proposed to minimize these deformations, including the use of spring-loaded compensators like the «Sila» node. The article describes experimental studies conducted to assess the load-bearing capacity of these nodes. The experiments included pull-out and compression tests conducted in the laboratory of SPbGASU. The results showed that the average destructive force for the pull-out test was 2 267 kN, significantly exceeding theoretical values according to current standards. In the compression test, the average maximum force was 364 695 N, approximately 10 % higher than theoretical calculations. The authors conclude that it is possible to increase the load-bearing capacity of these nodes by using stiffer springs. The article also provides a detailed discussion of the methodologies and results of the tests, analyzing the reasons for discrepancies between experimental data and theoretical calculations. Theoretical justifications and experimental data make this article useful for professionals in the field of wooden construction and engineering, as well as for those involved in the development and implementation of new construction technologies. The provided data and methods ensure reliable and durable log connections, reducing the likelihood of cracks and improving the operational characteristics of log structures.

Creep Coefficient for Self-Compacting Concrete (SCC)

With the development of construction technology, self-compacting concrete hasstarted to be widely used in the construction of buildings. The specific properties of selfcompacting concrete have made it particularly useful for concreting the structuralelements of high-rise buildings. The strains characteristics of concrete are important toknow both in the initial stage of concreting and in the long process, in order to takemeasures to minimize their impact on cracking and reduction of structure elements.In this regard we have conducted an experiment to investigate shrinkage strains andcreep strains in reinforced concrete beams as well as the determination of the creepcoefficient. Given that the shrinkage and creep strains are together, it is necessary toseparate the creep strains from the shrinkage strains to determine the creep coefficient.For the realization of this separation, we have prepared the same samples which havebeen used for the determination of shrinkage strains and samples which have beeninserted into the mechanisms for the realization of adequate force for thedetermination of the creep strains.

Numerical Study of Wind Flow Behavior Around High-Rise Buildings Using Computational Fluid Dynamics (CFD)

The development of civil construction technology in Indonesia is progressing along with the rise in high-rise building construction. The emergence of high-rise buildings has altered wind flow characteristics, leading to phenomena that can directly impact surrounding structures. One of the observable phenomena is the wind speed amplification caused by the narrowing of the wind flow section, known as the Venturi effect. This study aims to compare the outcomes of two Computational Fluid Dynamics (CFD) methods—Reynolds-Averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES)—against experimental results. The study employs a model of four buildings of similar height and symmetrical positioning, with a 72 mm passage width, to verify numerical simulations against experimental data. The RANS method yields a maximum wind speed amplification of 14.9% along the passage's centerline, which remains below the experimental prediction of 25.5% in Zone A. Conversely, the LES results show a higher wind speed amplification, reaching 40.2%, surpassing the experimental findings. Nevertheless, LES identifies a similar location for wind speed amplification observed in Zone A. Additionally, CFD simulations were conducted to analyze the effects of passage width, revealing that a passage width of 54 mm produces the highest wind speed amplification, with a ratio value of passage width to building influence scale (L/S) of 0.481. Further research on building model scale may be necessary to verify CFD accuracy compared to the actual scale. However, such simulations demand exceedingly high computational resources with current technology.

Analysis and Real-Time Monitoring of the Influence of Wind Load on a High-Altitude Steel Connecting Bridge with Small Spacing

With the development of steel-structure construction technology in high-rise buildings, the design and construction of high-rise steel structures tend to be complicated. Based on the Zhuhai Tiejian Square project, the fluid-structure coupling calculation analysis and on-site monitoring are carried out in view of the wind load of the high-altitude steel-structure connecting bridge in the hoisting stage of the Zhuhai Tiejian Square project. The main structure of the project is four towers and five high-altitude, small-spacing steel structures connecting the four towers. The lifting process of the third zone is taken as the analysis object, and the hoisting idea of “low-altitude hoisting, overall lifting” is adopted. Because the span of the high-altitude steel-structure connecting bridge is small and the installation height is high, the influence of wind load on the hoisting process cannot be ignored. Therefore, the unidirectional fluid-structure coupling model of the high-altitude small-space steel-structure connecting bridge in the third zone was established by using CFD calculation software ANSYS Fluent 2022 R1, and the corresponding flow field and solid calculation results were obtained and analyzed. The analysis results show that the lifting structure still produces a certain deformation when the wind speed is 5 m/s or 10 m/s, and the calculation results show that the stress calculation results are still within the safe range of steel strength for the sensitivity of the lifting structure under wind load. With the increase of wind speed, the local maximum stress of the structure increases greatly, but the overall deformation remains stable, which indicates that the greatest challenge of hoisting steel structures under wind load may be the stability direction rather than the strength, so it is necessary to strictly monitor the displacement deformation of the structure during construction. Then, through the monitoring of the overall lifting process of the high-altitude, large-span, steel-connected structure of Zhuhai Tiejian Square from pre-lifting to formal lifting, real-time monitoring and data analysis show that the lifting process of the high-altitude steel bridge of Zhuhai Tiejian Square is safe and reliable, the force transformation of each component is reasonable, the lifting process is relatively stable, the external environment has little impact, and the expected monitoring effect has been achieved. The calculation simulation and on-site monitoring in this paper can provide theoretical and practical guidance for the construction safety under the influence of wind load in the construction process of high-altitude steel-structure hoisting, and provide an important reference value for similar projects.

To analyze the impact of computer technology on architecture and to assess the perspective of this impact in the future. Conclusion. Today computer technology is used everywhere. The development of modeling and construction technologies provides new opportunities in the field of architecture. The use of computer technology at all stages of construction allows architects to create increasingly complex projects with high accuracy and efficiency. The use of new technologies in the field of architecture will allow to provide a more complex approach to design, which can cover more characteristics necessary to take into account. Generative design can be used to provide a more efficient and accurate design process. Virtual and augmented reality (VR and AR) provide a wide range of opportunities for designing and modeling architectural objects. With the help of BIM technology, an information model is created, which provides an accurate vision of the project as a whole. An important component of this technology is a single information space, a database. Artificial intelligence can create thousands of building options. The question of how to use resources more rationally (time, material, human) is one of the key issues of our time. Computer technologies help solve these problems and invent new methods of designing and building architectural objects. Ukraine, as one of the most digitized countries in the world, is rapidly introducing the latest technologies into the design work processes, which will lead to positive changes in the state's architectural image.

Building practice of energy efficient earthquake-resistance buildings

The article discusses technologies for constructing energy-efficient, earthquake-resistant buildings that have increased rigidity and strength in their main components. These technologies utilize structures with enhanced damping and active seismic insulation systems. Practical implementations, design features, and technological aspects are examined. An analysis is conducted on the characteristics of current technologies, the conditions for production and installation, repairability, and their impact on the building's energy efficiency during operation. Technologies are systematized and categorized based on their principles of seismic protection during the analysis process. The analysis was conducted based on the following main criteria: steel consumption, suitability of repairable technologies used, possibility of implementing seismic protection during building reconstruction, ability to withstand seismic effects, feasibility of implementation, and energy efficiency. It has been determined that traditional technical solutions to increase rigidity and strength, such as introducing structures with increased damping used for buildings with precast, monolithic, and precast-monolithic frames, require a significant amount of additional resources. These solutions are characterized by accumulation of failures in individual hidden elements due to seismic loads, low maintainability, and often decrease the energy efficiency of the building. The use of seismic energy-absorbing mechanisms with high efficiency can significantly reduce resource costs for construction and increase maintainability, thus improving the overall sustainability of the structure. Based on the findings of the analysis, the following recommendations are made for conducting further studies on active protection systems in terms of design, development of construction technology, and potential application in the renovation of existing buildings.
