| Abstract | ||
| The construction of high-rise buildings with increasing slenderness ratios presents both economic and engineering challenges. This study investigates the effect of slenderness ratio on the seismic performance of high-rise buildings in various seismic zones across the United States. The research employs non-linear and linear static analysis to assess the seismic response of slender high-rises subjected to ground motions representative of different US seismic zones. Key parameters such as lateral drift, inter-story drift ratio, will be evaluated to understand how slenderness influences building behavior under seismic loads. The findings aim to improve seismic design guidelines, optimize structural systems for slender high-rises, This research contributes to the development of safer, more resilient, and cost-effective high-rise construction practices in earthquake-prone regions. In this study, the author focuses on the behavior of the slenderness of high-rise buildings, taking six models with different width. the behavior of high-rise concrete buildings in various zip codes throughout the USA. The study was done according to ACI 318-14 and ASCE 7-10. A linear and Nonlinear static analysis was carried out using ETABS software. The seismic lateral loading on the flat slab with high-column inertia, with or without edge beams, was taken into consideration.Each model was considered to have a different slenderness ratio due to the height of the building, as the author had 20, 30, and 40 storey buildings, This study presented a design chart for any building dimensions (length and width) to guide the designer to the maximum height that can be achieved in any seismic zone. | ||
