ABSTRACT
ABSTRACT: A software package is developed to perform earthquake scenarios for estimating structural damage and human casualties. The first stage involves generation of microzonation maps for separately calculated regional seismic hazard. The seismic hazard can be probabilistic or deterministic where PGA and spectral accelerations or acceleration time histories are specified respectively for each cell on the engineering bedrock outcrop. In the second stage, representative soil profiles are defined for each cell and 1D site response analyses are conducted to calculate average PGAs and elastic acceleration response spectra on the ground surface. An envelope NEHRP spectrum is calculated for each cell based on site specific average acceleration spectrum to estimate short (T=0.2 s) and long (T=1 s) period spectral accelerations. In the third stage, vulnerability of the building stock is estimated with respect to number of buildings in each cell. A case study for Zeytinburnu, a district in Istanbul, Turkey is conducted to demonstrate the applicability of the software package.
