Abstract

Abstract: A method was developed for assessing physical vulnerability of building to coupled multi-hazard based on modified PTVA model. According to differences between vulnerability indicators under different disaster conditions, a multi-hazard physical vulnerability assessment index system was established. Initial single hazard vulnerability indexed and coupling hazard vulnerability indexed were obtained by using the modified multi-hazard PTVA model. Then two comprehensive physical vulnerability indices of the initial and the coupling were calculated respectively. The method was used in a typical area in Fujian Province. The application results show that this method can reflect the similarity and difference between physical vulnerabilities of different buildings to different coupling effects, and can improve the accuracy of multi-hazard physical vulnerability assessment.

Key words: multi-hazard, Papathoma tsunami vulnerability assessment(PTVA)model, physical vulnerability, coupling effect, vulnerability of building
