Seismic Performance Analysis of Unreinforced Masonry Wall Structure

Abstract

From the previous earthquake (Nepal 2015, Bhuj2001,Utharakhand 2005, Gujarat 2006 ) it is
observed that the seismic performance of masonry building is worst. Hence there is a need of retrofitting of
existing masonry buildings. The above need is incomplete without seismic performance of masonry buildings.
Before retrofitting of building the first step is to obtain its performance. In the present work it is proposed to
obtain the seismic performance of unreinforced masonry wall using non-linear static analysis with SAP2000
software. The present work investigates the seismic evaluation of unreinforced masonry (URM) walls when
subjected to seismic (lateral) loading. The work consists of modelling the geometry and property of masonry
wall. After which non-linear analysis was performed using SAP 2000 software. The present work is divided in
to two parts.(a) Revealing the size of finite element meshing suitable for modelling an unreinforced masonry
wall in SAP 2000 software.(b) Investigating the result of nonlinear static analysis performed on selected
model.
