Seismic Performance Assessment of High-Rise Buildings with Different Structural Systems

Thesis Abstract

Abstract
The seismic performance of high-rise buildings is a critical aspect in ensuring the safety and structural integrity of these complex structures during earthquakes. This thesis focuses on the assessment of the seismic performance of high-rise buildings with different structural systems to provide valuable insights into their behavior under seismic loading conditions. The study investigates various structural systems commonly used in high-rise buildings, such as steel frame, reinforced concrete frame, and composite systems, to evaluate their performance and response to seismic forces. The research begins with a comprehensive review of existing literature on high-rise building design, seismic analysis, and structural systems. This review provides a solid foundation for understanding the key factors influencing the seismic performance of high-rise buildings and the current state-of-the-art practices in seismic design and analysis. The methodology employed in this research involves numerical modeling and analysis using advanced structural analysis software to simulate the behavior of high-rise buildings under seismic loading. The models are validated against experimental data and industry standards to ensure the accuracy and reliability of the results obtained. The findings from the analysis reveal significant differences in the seismic performance of high-rise buildings with different structural systems. The study evaluates the structural response, deformation patterns, and failure modes of each system under varying seismic intensities to identify their strengths and weaknesses in seismic resistance. The discussion of the results highlights the importance of selecting appropriate structural systems and design strategies to enhance the seismic performance of high-rise buildings. Factors such as material properties, building height, structural configuration, and damping mechanisms are identified as critical considerations in improving the seismic resilience of high-rise structures. In conclusion, this research contributes to the understanding of seismic performance assessment in high-rise buildings and provides valuable recommendations for enhancing their seismic resistance. The study emphasizes the need for rigorous seismic design standards, innovative structural systems, and proactive mitigation measures to ensure the safety and durability of high-rise buildings in seismic-prone regions. Overall, this thesis offers valuable insights into the seismic performance assessment of high-rise buildings with different structural systems and serves as a valuable resource for researchers, engineers, and practitioners in the field of structural engineering and earthquake engineering.
