A Study on the Development of Seismic Fragility Function for Construction of Earthquake Damage Assessment System in Korea

A study on earthquake damage assessment is very important for the government to manage the disaster, in particular to rapidly respond and judge the situation systematically according to damage scale. Thus the National Emergency Management Agency in Korea is building the Earthquake Disaster Management System. In so doing, the National Institute for Disaster Prevention in Korea has made the related research on seismic fragility functions since 2005. Since the earthquake damage is evaluated in large region, this paper classified each structure according to the status and characteristics of structures, developed fragility functions on the classified structures, and applied the functions to the system. Fragility functions for bridges and railroad systems and others have been developed so far. Also, various methods such as capacity spectrum analysis and inelastic dynamic analysis are used in development of applicable fragility functions to Korea.
