ANALYSIS OF HIGH RISE RCC BUILDING ON SLOPING GROUND USING ETABS

Abstract

Hill buildings are different from those in plains; they are very irregular in horizontal and vertical plains. Hence, they are susceptible to severe damage when affected by earthquake ground motion. Analysis of buildings in hilly region is somewhat different than the buildings on leveled ground, since the column of the hill building rests at different levels on the slope. The other problems associated with hill buildings are, additional lateral earth pressure at various levels, slope instability, different soil profile yielding unequal settlement of foundation. The scarcity of plain ground in hilly regions leads to construct structure on sloping ground in plain region to construct high rise structure is predominantly known condition, but in case of hilly region it is very difficult. In this study the 3D analytical model of G+25 storey building is to be generated for symmetric and asymmetric case with varying type of frame configuration. Building models are analyzed and designed by E-TABS software. We are analyzing the high rise structures for seismic load i.e. equivalent static lateral force method and response spectrum method on sloping ground or hilly regions with varying sloping angles, symmetric frames and step back and set back with step back configuration with varying positions of  shear walls by using  E-TABS.
