Abstract: This study focuses on the seismic analysis and design of a multistory building using ETABS software to evaluate its structural performance under earthquake loading. The analysis was carried out in accordance with relevant seismic design codes, employing both static and dynamic (response spectrum) methods to assess structural behavior. Modal analysis was used to determine the building?s natural frequencies, mode shapes, and dynamic characteristics. The results revealed that the building?s response is primarily governed by the lower modes, with higher modes influencing the performance of taller structures. Inter-story drift, base shear, and member forces were evaluated and found to be within permissible limits, ensuring safety and stability. The structural elements were designed and detailed for ductility, strength, and stiffness to resist seismic forces effectively. The study concludes that ETABS provides an efficient and accurate platform for analyzing and designing earthquake-resistant multistory buildings, ensuring cosmpliance with design standards and enhancing the overall seismic performance of the structure.
