NON LINEAR SEISMIC ANALYSIS OF MASONRY STRUCTURES

Abstract

Nowadays, even though many new construction techniques have been introduced, masonry has got its
own importance in building industry. Masonry structures fail miserably under lateral loading conditions
like earth quakes and impact loads. The occurrence of recent earthquakes in India and in different parts
of the world have highlighted that most of the loss of human lives and damage to property have been
due to the collapse of masonry structures. Though an earthquake could not be prevented, the loss of
life and property could be minimized, if necessary steps could be taken to reduce the damages on the
existing masonry structures. This paper investigates the application ofNonlinear Seismic Analysis of
a masonry building using ANSYS software and check the efficacy of retrofit measuresto protect the
existing building.
