Modified fragility functions for offshore wind turbines considering soil-structure interaction subjected to wind, wave, and seismic loads

Investment allocation for offshore wind turbines (OWT) as an important class of structures is typically carried out through supporting decision-making approaches utilizing some fragility functions. This study attempts to deliver fragility functions for OWTs on monopile foundations accounting for soil-structure interaction (SSI) effects. Simultaneous wind, wave, and earthquake loads were considered probabilistically by adjusting their occurrence hazard levels for predefined damage states in diverse performance levels. The designated damage states in this study are defined based on collapse probability and some targeted performance levels which could be very straightforward to distinguish. The damage state detection is based on rotation in the connection section of the tower’s transition part to the foundation, which perceptibly reveals the effects of SSI on fragility functions. The expected results comprise modified fragility functions accounting for SSI effects contributing to less median spectral acceleration, more evidently rotational demands, further dispersions, and a subsequent dominant increase in the probability of exceeding performance limit states. Considering operational performance level, the most applied design performance level for turbines as an important class of structures, not considering the SSI effects could noticeably underestimate the demands and lead to high-risk decisions.

Performance evaluation of high-rise buildings using database-assisted design approach

In recent years, performance-based design (PBD) has gained attention and is sought to be the benchmark approach in the field of wind engineering. While the concept of performance-based design is well-accepted in earthquake engineering, it is yet to be embraced for the design of buildings to resist severe wind loads. This paper introduces a framework for the performance-based wind design (PBWD) of tall steel buildings using a time domain analysis that keeps the process of wind effects and the structural design process integrated, transparent, and fully auditable. From the perspective of PBWD, the main objective is to achieve a desirable performance level for a given hazard level, i.e., mean recurrence interval of extreme wind. The wind effects are directly related to the mean annual return of wind through a well-accepted simulation approach. A 180 m tall standard CAARC building is used for the case study to illustrate the proposed methodology. The wind load time histories are determined using the pressure tap data on exterior faces of the building measured in the wind tunnel. With the calculated wind loads, nonlinear dynamic analysis is conducted with various wind directions and mean wind speeds based on database-assisted design (DAD) approach. The key performance measures such as demand-to-capacity indices, inter-story drift, damage deformation index, and floor accelerations are calculated as a function of wind directions and mean wind speed. The obtained responses are used in conjunction with a local wind climatological database to determine the extreme wind effects for any specific mean recurrence interval. The performance of the steel building is evaluated for three performance criteria, including occupant comfort, operational, and continuous occupancy. The conducted performance assessment reveals that building fails to satisfy the serviceability requirement of drifts. However, the building satisfies the requirements for the occupant comfort and operational performance levels for strength design, while it also satisfies the continuous occupancy, limited interruption in Risk category II. The result reveals that the proposed framework provides realistic assessment of performance of the building incorporating the wind directionality and return period of the wind speeds.

Performance Impacts of Telework, ICT and Management Control

The aim of this study is to examine the relationship between implementing a higher level of telework and operational performance and explore the role of Information and Communication Technology (ICT) capability and Management Control (MC) mechanisms. More specifically, the study focuses on the role of four MC mechanisms (action, outcome, personnel and cultural controls), and three dimensions of ICT capabilities (internal use, collaboration and communication) by taking a Dynamic Capability View (DCV). The results suggest that mandated use of telework in response to a crisis (COVID-19 pandemic) has a negative impact on operational performance. However, higher levels of telework increase the scope and use of MC, which in turn improves performance. Accordingly, we conclude that MC positively mediates the negative effect of TW on performance.

In addition, academics and interested parties might bring the research findings to examine and perform more research.

Integrative analysis of diverse hybrid power systems for sustainable energy in underdeveloped regions: A case study in Indonesia

<abstract> <p>There is a goal for practical renewable electrification and renewable energy investments in underdeveloped regions. Indonesia's experience underscores the complexities and challenges in implementing such projects effectively. A study on the effects of various socio-economic factors on Carbon dioxide (CO<sub>2</sub>) emissions in Indonesia highlights the significant impact of forest area, urbanization, and industrialization on carbon emissions. A hybrid system consists of PV, a Biogas Generator, and a Wind Turbine that are successfully deployed. However, no economic analysis has been conducted to obtain the best configuration of the hybrid system. We propose to delve into the effective integration combination of hybrid power systems. In this study, we thoroughly analyzed hybrid power systems in underdeveloped areas using the HOMER software. We examined five different hybrid system configurations: Solely biogas, complete generator integration, a biogas and hydrogen combo, biogas coupled with a PV system, and biogas combined with a wind turbine. Our findings indicated varying levels of economic viability, operational performance, and environmental impact across the configurations, providing crucial insights for policymakers and stakeholders in underdeveloped regions like Indonesia. The results showed the Wind-Hydrogen and Hydrogen Only schemes as the most cost-effective, with a Total Net Present Cost (NPC) of, 969.27 and Levelized Cost of Energy (LCOE) at zhongwenzy.218. Moreover, while CO<sub>2</sub> emissions were similar across all schemes, around 27,744 kg/year, the All-Generator scheme had slightly higher emissions at 27,667 kg/year but led in electricity production with 29,101 kWh/year. These results underscore the importance of balancing cost, energy output, and environmental impact in hybrid power system schemes for underdeveloped regions.</p> </abstract>

EVALUASI KINERJA PILAR JEMBATAN LEMAH IRENG II BERDASARKAN PERFORMANCE BASED SEISMIC DESIGN

Lemah Ireng II Bridge is a type of box girder balance cantilever bridge located in Semarang Regency, Central Java, which was completed in 2014. The renewal of bridge loading regulations in 2016 consisted of SNI 1725:2016 for standard load and SNI 2833:2016 for earthquake load. Changes in earthquake loading regulations resulted in an increase in the ground surface spectra value in the short period (Sds, T=0,2 second) in the longitudinal direction by 38.47% and in the transverse direction by 45.39% as a result of updating the earthquake map and the earthquake response modification factor. To determine the level of bridge performance against the applicable earthquake regulations based on the pier structure parameters, the Non-Linear Time History Analysis (NLTHA) method is used. The NLTHA method uses seven deaggregated ground motion records which aim to represent the ground motions that occur at the bridge site. Parameter limits at the pier to determined performance level of bridge based on NCHRP Synthesis 440 and NCHRP Research Report 949. According to the results of performance-based analysis, the bridge pier structure meets the Fully Operational performance level based on the parameters of drift, compressive strain of concrete and tensile strain of steel reinforcement. At this level of performance, after an earthquake the structure suffers very little damage so no repairs are needed and the bridge can function immediately after the earthquake.

Towards a smart lean green production paradigm to improve operational performance

Over the past decades more and more production companies have adopted the lean paradigm to get operational performance improvements. More recently, the competitive environment is requiring an increasing attention towards sustainability issues leading to the implementation of practices to also improve sustainability performance and, in particular, the environmental impacts. The relationships between lean and green approaches in terms of their mutual influence in achieving target performance have been investigated in several studies (see for example (Dieste et al., 2019)– (Henao et al., 2019)). Most of related studies identify a supportive relationship between the two paradigms, and only few negative effects have been identified. Whilst the impact on performance in lean-green contexts has become a field of research in its own, little has been said in literature about how the new Industry 4.0 (smart manufacturing) paradigm and the emerging technologies, impacting in every area of a production company, can be of support to further strengthen the lean-green binomial (an exception is represented by (Duarte and Cruz-Machado, 2017)).This paper aims at proposing a framework to analyse how a smart environment relying on the Industry 4.0 tools and technologies can support the evolution of a lean-green company towards higher levels of operational performance. The final goal is to support practitioners in the strategic choice of what smart technologies to adopt in combination with selected lean and green practices to create an impact on selected operations strategy indicators or to identify initiatives to fill operational gaps in the context of a continuous improvement and radical innovations plans. Such approach may serve as a signpost for the shaping of operations strategies, especially in relation to technology management. In order to achieve the above-mentioned goal, a four-step methodology has been adopted to review the existing literature and to organize it in a way that allows highlighting the impacts of smart technologies, lean and green practices on performance indicators and to identify possible reciprocal influences. Eventually, to get a validation of the proposed approach, a semi-structured interview has been shared with four manufacturing small and medium-sized enterprises (SMEs) to get their perspective on framework potential benefits.

Operational excellence, organizational culture, and agility: bridging the gap between quality and adaptability

Operational Excellence (OpEx) is understood by the quest to continuously improve performance. While used by organizations worldwide, the capacity of OpEx programmes to make organizations successful in unstable business environments has been challenged. This article aims to answer the research question of what the nature of the relationship between OpEx and Organizational Agility truly is. The authors have previously proposed a theoretical framework supporting the link between Operational Excellence, Organizational Culture, and Organizational Agility. While built on a strong conceptual background, this framework lacked empirical validation. Following the conclusion of ten industrial case studies, this article provides a summary of the key findings obtained in each case and integrates them into an updated conceptual model. As key findings, this study shows how Operational Excellence enablers and cultural orientation have an important role in the development and scaling up of Organizational Agility capabilities, highlighting how different contexts may influence these dynamics. This article offers a better understanding of the balance needed to maintain high operational performance levels while dealing with change. It connects and upholds the importance of Organizational Agility and of the cultural paradigm in the management of Quality in technical and technological organizations.

HOW POSITIVE PSYCHOLOGY HELPS LEADERS CREATE INCLUSIVE, BETTER‐PERFORMING ORGANIZATIONS

AbstractThe author relates her experience applying the tenets of positive psychology to a manufacturing environment and explains how leaders in any sector can apply positive psychology for organizational success. Using this “in conjunction with lean manufacturing, a discipline based on creating value at the rate of customer demand built on the foundation of respect for the employees, resulted in multiple factories achieving significantly higher levels of operational performance. These factories were part of a $75 million division of a $12 billion diversified industrial publicly traded company that operates in fifty countries.” She relates the history of positive psychology, especially how “University of Pennsylvania professor Martin Seligman started a revolution, assembling researchers and psychology practitioners to work on the science of building well‐being.” She also explains the basics of the psychological concept associated with the late Stanford University professor Albert Bandura, self‐efficacy. She writes that “a leader’s self‐efficacy and the ability to create an environment where each workforce member can contribute to the business through their personal sense of self‐efficacy are critical ingredients in developing inclusive cultures.” Another important concept is optimism: “Leaders striving to create an inclusive culture for all the right reasons, including enhanced business performance, will benefit from optimism, a cornerstone of positive psychology.”
