Abstract - Unavailability of plain ground in mountainous
hilly area is not easy compared to building in plain ground. In some hilly regions of the world are more pronto seismic activity, In India, North and northeast part have large sloping grounds and construction of RC building is popular in sloping ground. Earthquake causes shaking of ground so building resting on slope will experience motion at its base. Even though the base of the building moves with ground. Roof has tendency to stay in original position. But since the walls and columns are connected toit, they drag the roof along with them. Earth quakes are the natural phenomenon which are caused by the release of large strain energy by the moving faults below the surface of the earth, which ultimately causes the shaking of the earth top surface in all possible directions with different amplitudes and intensities of lateral forces.
regions necessitated construction of framed building on sloping ground. In present study, the structure is totally commercial building. The structure is examined for seismic zone III and soil condition is hard consider. The structure is compared the sloping ground and plain ground and also with and with-out bracing system. The different model is done on STAAD.pro software. Some model is analysis on plain ground and sloping ground with-out Bracing system and some model is analysis on plain ground and sloping ground with- Bracing System. The different slope is 10degree, 20-degree and 30- degree is considered while analysis. The bracing is considered at outer peripherals and at Centre of core. The Models are analysis for various aspects like Story Displacement, Storey overturning moment, Storey Drift, Lateral Displacement, etc. In this research P-delta is not Consider. This help us understand detailed analysis of behaviour of building under different sloping angles and effect of earthquake on building.
1.1 LITERATURE REVIEW Ashraf. (1998) Ashraf et al. (1998) presents the steps used in performing a pushover analysis of a simple three-dimensional building. SAP2000, a state-of the-art, general purpose, three-dimensional structural analysis program, is used as a tool for performing the pushover. It allows quick and easy implementation of the pushover procedures described in the ATC-40 and FEMA-273 documents for both two and three-dimensional buildings. He suggested that it is easy to investigate the erect of different strengthening schemes and also to stiffen or strengthen the building by changing the member properties and rerunning the analysis.

In the hilly region having sloping ground it is hard to build the multistorey structures. The constructions of the building now days are progress on sloping ground due to lack of horizontal plain level ground. These hill regions are the most hazardous view shows sometimes due to some natural calamities like land sides and seismic activity.
Armagan Korkamaz Armagan Korkamaz et al. evaluated the performance of frame structures for various load patterns and variety of natural periods by performing pushover and non-linear dynamic time history analysis. Pushover and non-linear time history analyses results are compared to choose the best load distribution for specific natural period for this type of frame structure. They concluded that the shear failure of the columns is experienced at the larger storey displacements and rectangular distribution always give the higher base shear-weight ratio comparing to other load distributions for the corresponding story displacement. The rectangular load distribution shows maximum seismic demands during the given earthquakes more reasonable than the other load distribution
Earthquakes arise alongside plate margins (where inflate meets) while plate move fast, in the direction or farf rom other, the actions is not always so smooth. Friction causes the plates to get struck. This causes the pressure to build up of pressure released. Earthquakes are usually classified on the basis of causes of origin, depth of focus, Intensity and magnitude of earthquake. Earthquake is measured by using Ritcher magnitude scale anything is greater than magnitude 7 considered as sever type of Earthquake. Due to increase in population and rapid urbanization, the scarcity of plain ground is happened. Since structures are constructed in hilly area. The construction of building in
