In the study numerous buildings exhibit irregularities of their architectural plans, a feature that could render them susceptible to excessive seismic activities in the future. The purpose of this paper is to evaluate the seismic vulnerability and response of regular and irregular shaped multi-storey building of identical weight in context. Both static and dynamic (response spectrum) analysis has been done to observe the influence of shape of a building on its responses to various loading. G+12 storied regular (rectangular) and irregular shaped buildings have been modeled using program staad pro for seismic zone III. Impact of wind and static load on exclusive formed shape along with dynamic response spectrum has been meticulously analyzed considering the mass of each shaped is identical. A comparative analysis of the center of mass and maximum displacement overstorey of variously shaped buildings under static loading and dynamic response spectrum has been conducted. All form buildings react nearly in sync if the total mass fluctuates only little. But as the end result indicates, a structure's irregular dimensions are what expose it to its vulnerable direction. It is possible to build an irregularly shaped structure that might act more like a rectangular building while keeping the total mass the same.
