SEISMIC VULNERABILITY ASSESSMENT FOR BUILDINGS OF PORT BLAIR CITY USING RAPID VISUAL SCREENING AS A TOOL

Abstract

Andaman and Nicobar Islands is one of the most earthquake experienced areas around the world subjected to frequent earthquakes which is being the area of study using rapid visual screening (RVS) method by google maps and field visit as well. Although the google maps and internet sources can be used to cover up 80 percent data required for assessing and quantifying the RVS score but a field visit was made for extracting more relevant data for a detailed study. Port Blair municipal area was narrowed down for the screening since it had the greatest number of buildings. It was found that the moment resisting frames have been used in most of the buildings. RC moment resisting frames, load bearing structures, steel structures and wooden structures were studied in the screening and score was awarded. Gleaned from the score it was derived that old buildings are more susceptible for higher damage in near future then the recently constructed building.
