Comparative Study of C & L Shape Shear Wall in RC Flat Slab Structure

Chillu S Nandakumar | Nusra S ^[2]

Abstract: Flat slab construction possesses major and various advantages over conventional slab-beam-column construction. The flat slab systems structural efficiency is often hindered by occasionally poor performance under earthquake loading due to inherent insufficient lateral resistance. This undesirable behavior is mainly due to the absence of deep beams and/or shear walls in the flat slab system which generally gives rise to excessive lateral deformations. Shear walls are vertical elements of horizontal force resisting system. Shear wall with flat slab gives stability to structure as well as it improves lateral load resistance. This paper studies the effect of C and L shape shear wall in RC flat slab. The effectiveness of C and L shape shear wall in RC flat slab building is studied with the help of three different models such as flat slab building and C and L shape shear wall in RC flat slab building. Response spectrum analysis is carried out for the structure using ETABs software. The parametric study comprises of storey displacement, storey drift and storey shear in three structures. The comparison shows that the L shape shear wall is more effective to resist lateral loads compared to C shape shear wall.
