To reduce those losses and damages, it is necessary to understand the concept of structural vulnerability. With this in mind a project was undertaken by United Nations Development Program (UNDP) and Mymensingh Municipality in which a study was carried out to assess the structural vulnerability of the existing buildings of Ward no. 14, Mymensingh Municipality, Bangladesh. According to Bangladesh National Building Code (draft BNBC 2017), Mymensingh municipality is located in Zone 4 possessing an acceleration of 0.36g. This high acceleration can cause severe damage to buildings which were built according to BNBC 1993 considering an acceleration of 0.25g. For this purpose, total 707 buildings were assessed according to the guideline of FEMA P-154 which is known as Rapid Visual Screening (RVS) Method. Different vulnerability features e.g. soft story, plan irregularity, pounding etc. were focused in this assessment. The study reveals that about 53 percent buildings show the above-mentioned structural defects. About 36% buildings are below cutoff score (based on seismic design criteria) and are vulnerable to earthquake. 28% buildings are unreinforced masonry (URM) which are more vulnerable in earthquake. Different damage levels of the assessed buildings, recommended by European Macroseismic Scale (EMS-98), were identified. Above 97 percent of surveyed structures show a high probability of Grade 3 damage and a very high probability of Grade 2 damage. RVS scores of buildings are seen with respect to number of stories, usage and structure type. Using ArcGIS 10.5, vulnerable buildings of different damage grades are represented in a map which shows their spatial location and distribution in Ward-14.
