Title: Seismic Evaluation of Flat Slab Buildings with Shear Wall
Abstract: Flat slab system is being adopted in many buildings presently due to the advantage of reduced floor heights to meet the economical and architectural demands. Flat slab construction gives lesser floor-to-floor height for the same headroom. Generally, flat slab column system is designed in lower seismic zone areas for resisting gravity loading. Its performance reduces drastically as this system is introduced to lateral loadings of higher seismic zones. As IS code is silent about flat slab structure design provisions in higher seismic zones, while analyzing these structures in such zones, we must have certain provisions to get rid of its poor performance. Thus, to resist this lateral loading, this system is provided with lateral load resisting elements such as shear walls. This paper presents seismic behavior of 8, 12, and 16 storey flat plate buildings designed for gravity loading only. The behaviour is studied for seismic action corresponding to Zones IV and V of IS:1893-2002. Along with this, how its behavior varies and improves with the introduction of shear wall is studied using static nonlinear analysis, i.e., pushover analysis, and the results are presented.
