Prediction of seismic casualties based on the seismic damage index

Abstract:

For making up the insufficiency of HAZUS method,that is the determination of damage mean value in the HAZUS method is subjective and fuzzy,the Seismic Damage Index(SDI) in Park-Ang damage model is introduced to describe the structural damage status.Combining the theoretical frame of HAZUS method,a SDI-based prediction method of seismic casualties was proposed,and a six-floor concrete frame structure was analyzed with the proposed method.Results show the feasibility of the proposed method.
