Abstract

The aim of seismic evaluation is to assess the seismic capacity of earthquake vulnerable buildings or earthquake damaged buildings for the future use. It has been observed that majority of buildings damaged due to earthquake may be safely reused, if they are converted into seismically resistant structures by employing retrofitting measures. Retrofitting of buildings is generally more economical as compared to demolition & reconstruction even in the case of severe structural damage. The present work emphasize on the seismic evaluation & different retrofitting strategies of R.C. buildings. For this purpose a step by step procedure for seismic analysis is done for a four storey R C building according to IS 1893 (part 1) 2002, the demand capacity procedure is presented. The detailed calculations for demand & capacity of one of the perimeter framed - beam & column are presented systematically.
