Technical Note: SEISMIC DAMAGE EVALUATION OF EXISTING BUILDINGS BASED ON SHEAR WAVE VELOCITY: A CASE STUDY

Within minutes of shaking, the earthquake reveals the vulnerabilities of building structures, households, populace, and of a country. It acknowledges the influence of prevailing culture and way of life, on the capacity of the commonality to be preparedness for seismic hazard. Identifying buildings, whether having vulnerability or not is of critical importance both for reliable loss estimation as a result of an expected earthquake and setting priority criteria for strengthening of those buildings in order to save life and property. Few selected building stocks of Bhubaneswar Municipality (ward-7, ward-8, and ward-40) of Odisha State in India, were considered for damage evaluation corresponding to different construction typologies and soil characteristics. The RVS scores were correlated with damage potential. A total 2624 number of buildings were assessed during walk down survey. It was estimated that, a detail analysis needs to be performed on 890 buildings for calibrating RVS score but special attention should be given to 283 number of buildings with RVS score less than 0.7 as these buildings have the high probability of heavy damage.
