Abstract

This paper provides an in-depth examination of the effects of both earthquake and wind loading on high-rise buildings situated across various terrain categories and seismic zones. The research underscores the critical importance of accounting for lateral loads in the design of reinforced concrete structures, as this consideration is essential for maintaining structural stability and ensuring the safety of occupants. The study focuses on identifying the critical design loads for multistory buildings subjected to varying wind speeds, specifically 39 m/s and 50 m/s, as well as seismic forces corresponding to seismic Zones II and V. The analysis is conducted in strict adherence to the IS 1893:2002 code for earthquake loads and the IS 875:2015 code for wind loads, ensuring compliance with established safety standards. By meticulously evaluating the response of high-rise buildings under these diverse conditions, the study aims to identify the predominant design loads that should be prioritized for structures located in specific wind and seismic zones. The findings reveal that high-rise buildings are significantly influenced by both wind and seismic forces, with the results indicating that wind forces can impact high-rise structures in a manner comparable to seismic forces. This highlights the necessity for a comprehensive and integrated design approach that accounts for both types of loads to achieve optimal structural performance and safety. The research contributes valuable insights into the complex interplay between wind and seismic forces, emphasizing the need for careful consideration of both in the structural design of high-rise buildings.
