Test of a PSHA Map of China with Fortification Benefit Evaluation

Abstract A path for testing a probabilistic seismic hazard assessment (PSHA) map is presented in this paper via the evaluation of fortification benefit with two indices, economic and safety benefit. The effect intensity on vulnerability engineering structure emphasized damage estimation evaluation. expected losses casualties are calculated based total areas each five states local parameters. result case study 1990 PSHA China shows that reduction loss from to brick concrete reinforced buildings constructed during in-service period damaged subsequent destructive earthquakes RMB 216.5 billion. Thus 17.5 billion comparison additional cost 199.0 casualty reductions 20,838 fewer deaths 77,801 serious injuries. This indicates implementation has indeed played beneficial role earthquake disaster mitigation. marginal fortification, terms increasing or decreasing intensities by one degree further whole country, level adopted appropriate as whole.
