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. Keywords: Old Masonry Structures, Earthquake damages, Seismic design, Base shear, IS code provisions.
I. INTRODUCTION Brick and stone Masonry are the most utilized construction technique of ancient buildings other than wooden work. Stone/Brick Masonry has been utilized in a Wide assortment of structures for public and residential structures in the past thousands of years. From the Tower of “Babylon” which ought to have reached the sky on the off chance that it had been finished, to the Great Wall of China, which is the main man-made structure noticeable from the Moon. An incredible number of very much protected old masonry structures still exist, demonstrating that masonry can effectively bear loads and environmental impacts, along these lines giving shelter to individuals and their goods for a significant period of time, if sufficiently considered and constructed. In acknowledgment of their significance and value, huge numbers of those structures have been positioned among the assets of the most noteworthy classification of mankind's historical and cultural heritage. A. DAMAGE TO HERITAGE STRUCTURES IN INDIA DUE TO EARTHQUAKES, IN THE SPAN OF LAST 15 YEARS India has witnessed six earthquakes of moderate intensity, even if moderate in intensity, these earthquakes have caused to a great extent huge amount of losses to property, which highlights the exposure of the infrastructure to earthquakes. The trembling of 1993 and the Bhuj quake of 2001 which caused big injure to properties highlighted the need to focus upon long-term seismic improvement and attentiveness in series to moderate the money-spinning losses caused because of
