the demand of space on the hilly areas is increasing day by day. the construction of slopes on hilly areas has to be considered to complete this demand. Seismic analysis is a static linear analysis which is used to predict the failure caused by the earthquakes before it happens. In this thesis G+5 model has been analysed resting on different sloping angles 0degree, 15-degree, 30 degree. This G+5 model is analysed by software ETABS 18.0.2. models are analysed on the plane and sloping areas. Firstly, seismic analysis is performed on the model assigning load cases and load combinations. After applying all the loads and all the lateral loads on the G+5 Model the model is set to run analysis. After running analysis, the results have to be compared such as storey drift, storey shear, overturning moment, maximum storey displacement. after analysing the results, the graph plotted according to the results came. All the loads are applied according to IS code 1893:2016 part 1. Storey shear is a graph that shows how much lateral (horizontal) load is acting per storey, whether from wind or seismic activity
The present work aims at providing a simple approach For analyzing the G+5 model resting on plane and sloping ground and to compare the results of storey drift, storey shear, overturning moment, maximum storey displacement.

To compare the lateral displacement of multi-storey building resting on plain and sloping ground at different sloping angles with respect to the multistorey building resting on plain ground.
To compare the behaviour of sloping ground structures at different sloping angles in different seismic zones with the same loading and structural frames.
To study the effect of lateral forces on short columns and long columns of multi-storey building resting on sloping and plain ground.
1.2 Methodology:
Due to the structural irregularity, seismic forces are more severe in hilly terrain. In addition, earthquakes are more likely in steep terrain, according to research. The north-east Indian states, for example. The distribution of mass and stiffness in both the horizontal and vertical planes of a structure determines how it behaves during an earthquake. Both of these qualities are affected by irregularity and asymmetry in hilly regions. Shears and torsion are more likely to occur in such structures in seismically active places. The architecture in the hills differs from that on the plains. In horizontal and vertical planes, they are exceedingly uneven and asymmetrical lead to destructive earthquakes process of dislocations segments is caused by the waves known as seismic waves. Earthquake is a type of natural disaster and its consequences are often disastrous. Basically, earthquake can cause effects due to multistorey as well high-rise buildings running text should match with the list of references at the end of the paper.
