CONDITION ASSESSMENT OF BUILDING USING RAPID VISUL SCREENING PROCEDURE

Abstract

With the occurrence of a number of earthquakes in the past and chances of many more in the future, seismic risk assessment has become a key factor in the seismic risk mitigation and management. Seismic design for structure has evolved with the passage of time and so has the complexity in design and construction. Seismic design has its own limitation. Every types of structure deteriorate with time and become seismically vulnerable. Seismic vulnerability also depends upon the quality of construction and uses of structure. In a country like India where population is large, the number of building vulnerable to seismic condition present a difficult situation in regarding to life safety. India is a developing country where construction work is increasing day by day very fast to cope up with the present growing requirement. Due to poor economical conditions many buildings are not in a good condition, hence a very rapid, reliable and economical method is required to roughly judge the seismic safety of buildings. Rapid Visual Screening of building structure appropriately serves the purpose. In the present work, various aspects of Rapid Visual Screening (R.V.S.) are considered. Rapid visual screening practices in US as per FEMA 154 and those in India are studied and an overview of topic is developed. Later on efforts are made to devise a new more accurate and quicker R.V.S system for Indian conditions. This new RVS system is proposed in detail and explained. With the help of this RVS system the various building of BSES Yamuna Power LTD is screened and the Result obtained and compared.
