Chittagong, GIS, performance, seismic vulnerability, medical facilitiesAbstract
Medical facilities are one of the most important lifelines that need to remain functional
during and after an earthquake. Bangladesh is a multi-hazard prone country located in the
southern part of Asia where a significant number of natural disasters are recorded each year. The
second largest city and economic hub, Chittagong, is located in the south-eastern part of the
country, falls in the seismically moderate zone as per Bangladesh National Building Code
(BNBC 2017) with a seismic zoning coefficient of 0.28g based on 2 percent probability of
exceedance in 50 years. Most of the buildings were built before implementation of seismic code
practiced in Bangladesh. Based on growing need for developing disaster risk plan, seismic
performance is evaluated for existing important medical facilities by applying simple visual risk
assessment procedure. The structural database is developed through field survey and result of
seismic performance is presented in Geographic Information System (GIS).
