This document presents research on analyzing the seismic performance of flat slab structures under static and dynamic loads. Models of flat slab structures with varying lateral stiffness were created, from flexible columns only to stiffer combinations of columns and shear walls. The models were subjected to seismic and dynamic loads, and the structural responses like natural periods, base shear, displacement, and inter-story drift were studied. The results showed that providing edge beams and shear walls strengthened flat slab structures seismically. Key aspects analyzed included the natural period, base shear, displacement, and inter-story drift of flat plate and flat slab structures with different configurations, under static and dynamic seismic loads.
