Seismic analysis plays a crucial role in assessing the structural performance of multistoried buildings subjected to earthquake forces. This abstract presents an overview of a study conducted on the seismic behavior of a multistoried building with both rigid and semi-rigid diaphragms. The objective of the analysis is to evaluate the structural response and identify the influence of diaphragm flexibility on the building's seismic performance. The study employs a numerical modeling approach, utilizing finite element analysis (FEA) software to simulate the building's behavior under seismic loading conditions. A three-dimensional (3D) model of the multistoried building, considering different heights and configurations, is developed. Two distinct diaphragm types, namely rigid and semi-rigid, are incorporated into the model to investigate their effects. The rigid diaphragm represents a traditional assumption in structural analysis, assuming perfect rigidity and full transfer of lateral forces across the building's floors. On the other hand, the semi-rigid diaphragm incorporates flexibility by considering the rotational and translational stiffness of the floor slabs. Through the seismic analysis, various key performance indicators are evaluated, including displacement, Time period, and column forces.
