analysis is to determine how a structure will behave in response to a given action. One of the main causes of a building's poor performance under high seismic loading is structural symmetry. One important factor contributing to a building's poor performance under high seismic loading is structural asymmetry. Structural asymmetry can be a major reason for the poor performance of buildings under severe seismic loading. In this paper the analysis of seismic behavior of symmetric plan of multi-storied buildings by using STAAD Pro.

is referred to as multi-story. The goal of multi-story buildings is to save money by expanding the building's floor space without expanding the surrounding land area. An Earthquake can cause damage or collapse of buildings if not designed for lateral loads. The Shear walls are the structural elements which counters the effect of lateral loads such as with a symmetric distribution of stiffness and strength in plan undergo coupled lateral and tensional motions during earthquakes stiffness. The necessity to assess seismic performance buildings was highlighted by the recent earthquakes, which resulted in significant damage or collapse of numerous reinforced concrete structures.

When creating a structure that can withstand an earthquake, one of the most crucial factors is not just making sure that it can withstand the force acting on it, but also making sure that the building to be ductile enough to transfer this energy and dissipate it. Structural engineers must do both static and dynamic analysis when designing structures in accordance with qualitative seismic design guidelines. While their objectives differ, seismologists and earthquake engineers both use seismological data to better understand earthquakes and their impacts. It is important to make modifications to the seismic behavior forecast of currently constructed buildings. For this reason, studies on the seismic susceptibility of buildings have been created in order to assess the predicted level of damage in various building types. A few things are taken into consideration when designing earthquake-resistant constructions. The elements include the structure's inherent frequency, damping factor, kind of foundation, building significance, and ductility. Seismological data from numerous earthquakes were gathered and examined in order to map and comprehend the earthquake events. Seismologists concentrate on the worldwide problems associated with earthquakes and are primarily interested in geological elements, which includes earthquake prediction.. Simple regularly shaped buildings sustain far less damage than those with

LITERATURE REVIEW [1] B K Raghuprasad1, Vinay S2, Amarnath.K3 ; Studied “Seismic Analysis of Symmetric and Asymmetric Buildings in Plan: An asymmetric spring model's natural frequencies are higher than a symmetric spring model's, and the rotations about the vertical axis through the mass centre of an asymmetric model are lesser than those of symmetric model. Maximum displacement of asymmetric column model due to an earthquake ground motion (eccentricity 17%) is greater than that of symmetric column model. Simple regularly shaped buildings sustain far less damage than those with irregular configurations. The base shear of an asymmetric 11 story building (eccentricity 11%) is larger than that of a symmetrical 11 story building.
