Evaluation of Seismic Performance of Building Resting on Plain and Sloping Ground Under Seismic Load

Abstract

The Greatest challenge for the structural Engineers in today’s scenario is constructing the seismic
resistant structures. Structures are generally constructed on the level ground; but due to scarcity of level grounds the
constructions have been started on the sloping grounds. The behaviour of the buildings during earthquake depends
upon the distribution of mass and stiffness. The buildings constructed on sloping ground are subjected to severe
earthquake and are more prone to destruction. A study has been carried out by static and dynamic analysis on the
building resting on a plain ground, set back building on plain ground, step back and set back resting on sloping
ground and step back building on sloping ground. In the present study, Time history analysis for Bhuj, Nepal and
Sumatra earthquakes is carried out by considering parameters such as Base Shear, Roof displacement, Torsional
moment in beam, Axial force and moments for column. Earthquakes are applied at various angles to the buildings
and most severe analysis is studied for each case
