Abstract: This paper proposes the uses of nonlinear static analysis of masonry building for seismic assessment behavior. In this methodology consist push over analysis on the modal building. The push over analysis is a more realistic assessment of seismic vulnerability. Since it can give a higher number of possible failure mechanism then in the pushover analysis restricted to the two principle directions of the structure. according to this method the peak story drift, displacement and shear obtained from response spectrum analysis can resolve in to their translation and rotational components and related lateral forces and moments can be calculated. The development of result of pushover analysis using constructed load pattern is consider the seismic demand of the structure. The target displacements of the nonlinear static analysis can be calculated using the available codes IS 1893-2016, IS 456-2000, ASCE 41-13, FEMA-356, 213 and ATC-40.
