A New Method For Vulnerability Analysis And Application In Rural Dwellings

With regard to the characterization of structural vulnerability, a new definition of seismic vulnerability index and the corresponding formula are given. The new formula is merely associated with the vulnerability matrix, which shows that the contribution of different damage grade to the vulnerability index is different. Finally, based on earthquake damage matrix, the vulnerability index of three rural structures including brick-wood structure, civil structure and masonry concrete structure is presented. The seismic capacity of rural dwellings can be analyzed by vulnerability index.
