Abstract: The earthquake resistant design of structures as indicated by the existing design philosophy aims to guarantee that amid their lifetime, the structures resist the extreme possible tremor without collapse. This philosophy disregards the fact that for the allowable damage towards the end of the design life, it is important to represent the seismicity of the area in an extensive way i.e., in terms of magnitude with appropriate spatial distributions around the site. Interest for structural masonry has expanded essentially in recent years. Therefore, further advanced codes of practice for the design of structures in masonry have been presented in numerous countries. The threat of seismic tremors have underlined the requirement for wide monitoring and safety assessment of architectonical heritage. The research work is on examining the seismic vulnerability of a particular monumental masonry building: RANI MAHAL, at Islam Nagar in Bhopal, M.P (India). The seismic behavior is assessed by the equivalent static analysis, as indicated by IS 1893:2002(PART-1). Design of base shear for the palace with the data available after visual inspection of the palace determines the seismic strength/shortcoming of this sort of building to endure broad harm under earthquakes. The need of examining the structural behavior can further permit the identification of an appropriate retrofitting procedure if any harm is caused to the building by seismic tremors during its lifetime.
