Preliminary Study on the Fragility of Building Structures in Taiwan

This paper describes procedures of fragility analysis for building structures in earthquake loss estimation methodology in Taiwan (Haz-Taiwan system). The main objective of this paper is to define the building classification, relative damage states and provide the fragility functions for the general building structures in Taiwan that by utilize the available data. First, the available classes of the building structures in Taiwan are reviewed and a classification based on the available data to be implemented in Haz-Taiwan system is proposed. Second, the description of failure mechanisms and performance criteria based on the collected experimental data for different damage states that adopted in this research are proposed. Third, the theoretical methodology of the fragility analysis for the adopted building classes is introduced. Parameters for describing the fragility functions for each class are also generated and shown in the Table.
