A Study of soil structure interaction effects on earth quake response of RC frame structures

The structural integrity and stability of irregular buildings under lateral forces such as wind and seismic loads pose significant challenges in modern construction practices. Irregularities in a building's geometry and mass distribution can lead to uneven force distribution, making the structure more vulnerable to lateral displacement and potential failure. To enhance the resilience of such structures, shear walls and bracing systems are commonly employed to improve lateral load resistance.
This study conducts a comparative analysis of shear walls and different types of bracing systems, focusing on their effectiveness in minimizing lateral displacement, reducing base shear, and enhancing overall structural stiffness. Using numerical modeling and finite element analysis, the research evaluates various configurations and placements of shear walls and bracings in irregular buildings. The study aims to identify the most efficient structural system for optimizing building performance under different wind and seismic loading conditions.
The results provide valuable insights into the behavior of irregular buildings with shear walls and bracings, helping engineers and architects select the most suitable structural design to ensure safety, stability, and cost-effectiveness. The findings can contribute to the development of improved construction guidelines and design standards for irregular high-rise and mid-rise buildings in earthquake-prone and high-wind regions.
