Abstract: Seismic forces are irregular in nature and unpredictable hence the static and dynamic investigation of the structures have turned into essential worry of structural Engineer. The main reason for the failure of the building is due to the plan irregularity of the RC multistory building. So, as it’s fundamental to detect the seismic response of the structure in high seismic zones to decrease the seismic harms in structures. The main objective of the present study is to obtain the seismic response of the structure i.e. (Displacement, overturning moment ,story drift ,story shear) for G+18 building and to compare these seismic response for the different geometry of the building i.e. (Box-shape, L-shape, T-shape, Tube-shape, H-shape and Cshape) by ETABS 2016 software to conclude the most stable structure among all these shape. Analysis of models were performed by Static and dynamic analysis. And further the comparison in term of displacement between Static and dynamic analysis is performed to evaluate the most economical and best method. The result shows that box shape building is more stable comparing to all other shape of the building and dynamic analysis method is economical and it predict the accurate result then Static method.
