Seismic Analysis of Old Masonry Buildings using Equivalent Static Method

Abstract

In heritage protection, there is vital necessity to recognize the impending seismic risk in prevailing historic buildings for hazard moderation, disaster alertness and preceding knowledge of probable hazards. Seismic risk estimation remains centered on safety assessment which necessitates qualitative and computable data. This data is necessary before making slightly intervention verdict. The qualitative data is visual inspection of degenerations, structural damages and depreciations; and the computable data requires laboratory tests, structural analysis etc. Obtaining the computable data is thorough method, which demands specialists and takes extra time and money. The fact that there are numerous historic buildings and a limited professional on this arena, it is very significant to create condition survey based on visual inspection as a first step of safety assessment technique. Conferring to these results inevitability of detailed examination and intercession and renovation works can be ranked. This work aims at existing condition survey standards in general and laid emphasis on visual examination of the structure. The data given in this research is a visual examination method for judging the risk level of masonry monumental historic structures and then numerically analyzing the building by using equivalent static method and finally comparing the base shear, ensuring the safety of the structure from the damage due to seismic effects. The dissertation deals with Chaman Mahal, Bhopal (MP), as a case study.
