INFLUENCE OF SLOPING GROUND ON THE SEISMIC ANALYSIS

Abstract

Seismic investigation is the computation of the reaction of a structure to quakes. It is a piece of the procedure of auxiliary plan, seismic tremor building or basic evaluation and retrofit in districts where quakes are common. The aim of this paper to study the response of RC structure on slopping ground.  To  evaluate the response of building by using linear analysis and non linear analysis. The analysis will be carried out on SAP2000 with help of guidelines following code I.S1893:2002 (part I), FEMA 356. The seismic reaction on slope ground is quite dissimilar as compare to seismic reaction on simple ground. In Reinforce concrete structure design we will not take the effect of infill wall on structure at the time of earthquake. In addition to this infill walls have a considerable strength and inflexibility and they have main effect on the seismic reply of the structural system. Requirement of analysis the seismic response of Reinforced Concrete building on inclined ground because require of timely revision of codes of practice and standards. Mount buildings are dissimilar from those in flat surface; they are very unequal and asymmetrical in horizontal and vertical planes, and torsionally coupled. Due to the diverse configurations of building in mountainous areas, these buildings become highly irregular and asymmetric, due to difference in mass and rigidity distributions on dissimilar perpendicular axis at each floor. Such buildings are seismically level areas makes them showing to greater shears and torsion as compare to conservative construction.
