Abstract:

Earthquake is an unexpected and expensive disaster for both livelihood and economy. In the present day construction, there has been a lot of importance to make the structure resistance against lateral loads for multi storied building, Structural walls are an option of lateral loads resisting system (LLRS) in buildings. They attract lateral loads due to their high-in-plane stiffness as compared to other members in the structure. The presence of structural wall allows the designers to design other members to take gravity load only. A well designed and detailed shear wall can provide the required strength as well as sufficient ductility for resisting lateral loads and can prevent high damages. The increased use of shear wall in buildings has triggered the necessity to study the behaviour of the wall under various modelling conditions. In the present study a typical low rise building is considered with two types of modelling the structural wall, one with multi-layer shell element and other with equivalent column element. The results obtained were compared with a normal frame building designed to with stand lateral loads without shear wall. The building was analysed using SAP2000 (V-17.3). From the analysis, it was observed the pushover curves observed for multi-layered shell element and equivalent column elements are almost equal. Hence, the modelling of structural wall as a column element can predict the behaviour similar to multi-layered shell element.
