Most of the hilly regions of India are highly seismic. Buildings on hill slopes differ in a way from other buildings. The soft storeies are typical feature in modern constructions specially in seismic areas which has been experience by the previous studies and past earthquakes. Due to verious type of structures on sloped ground structures are comes under irregularity and asymmetricity. Structures on slope leads to seismic cases.The damages to the structures are determined and acceptable safety can be provided. The linear-elastic analysis is not adequate in highly seismic areas. Thus for the design of building in seimic areas and sloped areas inelastic procedure is used. In the present dissertation work, 3D analytical model of eleven storeyed buildings on plain and curved ground have been generated. Models are analyze using ��ETABS�to get the behavior of structure due to change in column height in ground story due to curved sloped ground. The analytical model of the building includes all important components that influence the mass, strength, stiffness and deformability of the structure. To study the effect of infill, concrete shear wall and concrete core wall during earthquake, seismic analysis using both elastic and inelastic method of analyses i.e., linear static (equivalent static method), linear dynamic (response spectrum method) has been performed. The deflections at each storey level has been compared by performing equivalent static method, response spectrum method. Storey drifts are within the permissible limit given for linear static and linear dynamic method. Again contrary to common practice, the presence of masonry infills, concrete shear and concrete core wall may affect the overall behavior of structure while subjected to earthquake forces.
