SEISMI RISK MANAGEMENT OF AN INTERNATIONAL PORTFOLIO OF BUILDINGS
The British Council operates i 110 countries worldwide and needs to manage the earthquake risk i the buildings it works i .Accordingly,it commissioned a desk study i tended to create a shortlist of buildings that required detailed on-site seismic inspections.85 buildings i 60 countries were chose for the desk study,i areas where the seismic hazard exceeded a rock PGA of 10%g for a 475 year retur period.Information on the structure of the buildings was obtai ed by means of a specially prepared questionnaire,designed to be completed by the (non-specialist)local ma agers of the buildings.The seismic hazard at the sites was re- evaluated,based on a variety of readily available sources,to account for local soil and seismological influences on ground motions,and a 475 year retur period intensity value was calculated at the site of each building.The structural and intensity data were the used to evaluate the risk of collapse and risk of death,based on databases of building damage and huma casualties i earthquakes prepared by CAR Ltd.For buildings where these risks exceeded defined thresholds,an on-site assessment by a suitably qualified seismic engineer was recommended.The study e abled British Council to understand better the risk that earthquakes posed to staff and other users of its buildings,and to compare it to other risks such as fire.It also proved to be a cost effective way of identifying pote tially high seismic risk buildings which needed a on-site inspection to determine possible seismic retrofitting measures.
