STUDY OF BEHAVIOUR OF FLAT SLAB WITH BASE FRAME, SHEAR WALL, STEEL BRACINGS, INFILL WALL UNDER SEISMIC LOADING BY PUSH OVER ANALYSIS

Abstract

Flat slabs are becoming popular now a days as they are aesthetically good in appearance and ease of construction. But they are prone to earthquake and wind forces. Lateral resisting system has to be used to increase the strength, stiffness and lateral force resistant of the structure. In the present study four different models are taken for study and those are flat slab bare frame, flat slab with shear wall, infill wall and steel bracings. They are placed in one opposite direction for study in particular direction. Response spectrum analysis are conducted on different models to study the dynamic behaviour. Based on this analysis time period, base shear, lateral displacement and storey drift is compared. Pushover analysis is also studied on different models to known the weak zones in the building. Flat slab with shear wall model is stiffer and can resist lateral force effectively
