Design Of Multistorey Earthquake Resistant R.C.C. Frame with Shear Wall using ETABS

Abstract

This thesis discusses importance of the lateral stiffness of a building on its seismic design. Buildings that are laterally more flexible attract less seismic force but undergo higher deformations during the earthquake shaking. To reduce damage in the event of an earthquake, it is desirable to have large lateral stiffness. Shear walls contribute significant lateral stiffness, strength, and overall ductility and energy dissipation capacity. This report briefs out the shear wall system, which is widely adopted system because of its strength, stability and stiffness to resist lateral loads. Shear walls have considerably stiffness in their own plane but usually very little stiffness in the perpendicular direction and their satisfactory performance depends on the stiffening effect of floor diaphragms, which prevent buckling of walls. It is advantageous for shear walls to carry as much gravity loads as possible to minimize the danger of tension or overturning by the lateral force. ETABS (Extended Three-dimensional Analysis of Building Systems) is selected as software for the analysis of the building system as it is special purpose software of SAP series, based on Bureau of Indian Standards (IS 456-2000 and IS 13920-1993). The objectives of this study are to understand the shear wall behaviour, to design the multistorey building using the various structural systems and to compare the same.
