Considering the effect of seismic forces on high rise structures in sloping area

As most of the northern zone of India is situated in mountainous region, there is a lack of plain surface. (India is number two in population in the world there fore to settle this population there is a high demand of high rise structure). But in areas where plain ground is not available therefore high rise structures are to be built on sloping ground subsequently, the primary target of this study is to decide the effect of seismic forces on the high rise structures. Situated on a sloping ground for which in this dissertation slopes of 0 degree, 8 degree and 12 degree is considered with different soil conditions to find out the effect of different soils too. Comparative study have been made on unsymmetrical plan of G+9 floors considering all the four seismic zones as per I.S. 1893 part 1 2002. For analyzing and modeling purpose STAAD. Pro programming is utilized and study is done on the premise of maximum storey displacement, axial forces, shear forces, maximum bending and displacement in X and Z direction. In this study we adopt 13 loading combination in each case as per Indian Standards and dimensions of column (450 mm × 450 mm) and beam (400 mm x300 mm) in all the cases. We observed the result of all the cases in the same manner, Soft soil shows maximum values in all parameters, medium soil shows moderate result and hard soil shows minimum.
