Development of buildings vulnerability functions in subsidence regions

Extraction of ore and mineral by underground mining is often the cause of groundsubsidence phenomena. In urban regions, these phenomena may induce small to severedamages to buildings. To evaluate damages, several methods have been developed indifferent countries. These methods may be classified into empirical and analyticalmethods. Application of these methods and their comparison is difficult due to thedifference of the number of criteria used (between 1 and 12) and the results of the damageevaluation may be significantly different. This paper deals with the development ofvulnerability functions based on a concept used in other area such as earthquakeengineering. A methodology is described for the calculation of vulnerability functions insubsidence zones by the use of empirical methods. In this paper the methodology ofdetermination the vulnerability and fragility curves are explained.
