Buildings constructed on slopes are different from those in plains. they'll be irregular and unsymmetrical in horizontal and vertical planes, and torsion ally coupled. Hence, they're vulnerable to severe damage when suffering from earthquake ground motion. We can’t avoid the longer term earthquakes but the preparedness and safe building construction practices for earthquakes can certainly reduce the extent of injury and loss of both property and life. this is often thanks to the very fact that the columns within the ground storey are of various heights in such how that column in one end may be a short column and column in other end may be a long column. Dynamic characteristics of hill buildings are somewhat different than the buildings on flat ground. Torsional effect of such buildings is broken for having the difference stiffness and mass along horizontal and vertical plane during ground motion .Short columns of RC frame buildings damage due to attracting more forces during earthquake. The work is concentrated to research 2-D frame of (G+9) building on plane and on sloping ground at 45degrees ,65 degrees using ETABS software when seismic loads are incorporated.
