--------------------------------------------------------------------------***----------------------------------------------------------------------Abstract The investigation presented in this paper aimed at predicting the seismic response of RC buildings with different configuration on sloping & plain ground. A seismic analysis performed on G+6 story RC structural & steel structural building. 3-D Analysis including seismic effect have been analysis method by using STAAD PRO. Here we have four configuration rectangular RC structure on plain and sloping ground and Rectangular steel structure on plain and sloping ground building were considered for analysis and they are rested on 0 & 10 slope. From the analysis of dynamic parameters obtained and has been discussed in terms of Horizontal moments, Seismic base shear, Axial forces and Displacement.

Introduction
In some parts of world, hilly area is more prone to seismic activity; e.g. northeast region of India. The Tourism and rapid urbanization in hilly region has accelerated the real estate development. Due to this, population density in the hilly region has increased continuously. Therefore, there is demand for the construction of multi-storey buildings on hill slope in and around the cities. Hill buildings are different from those in plains; they are very irregular and unsymmetrical in horizontal and vertical planes, and torsionally coupled. 1.1 Aim To study the behavior of RCC and steel building resting on Plain and sloping ground. 1.2 Objectives The objectives of project are as follows:-
To compare various structural parameters for buildings resting on plain ground. To study behavior of RCC and Steel frame in various seismic zones. To study the variation in material requirement for framing material. To find the most vulnerable framing system amongst all frames conditions. To find various parameters for all frames Such as, Axial forces, Bending Moments, Displacements and compare them.
1.3 Need of Study Hill buildings are different from those in plains; they are very irregular and unsymmetrical in horizontal and vertical planes, and torsionally coupled. Hence, they are susceptible to severe damage when affected by earthquake ground motion. Past earthquakes [e.g. Kangra (1905), Bihar- Nepal (1934 & 1980), Assam (1950), Tokachi-Oki-Japan (1968), UttarkashiIndia (1991)][1], have proved that buildings located near the edge of stretch of hills or sloping ground suffered severe damages. Such buildings have mass and stiffness varying along the vertical and horizontal planes, resulting the center of mass and center of rigidity do not coincide on various floors. This requires torsional analysis; in addition to lateral forces under the action of earthquakes. Little information is available in the literature about the analysis of buildings on sloping ground. The investigation presented in this paper aimed at predicting the seismic response of RC buildings with different configuration on sloping and plain ground
