基于地震损伤指数的地震人员伤亡预测方法

Prediction of seismic casualties based on the seismic damage index

为弥补HAZUS方法在损伤中值确定中存在的主观性等不足,引入Park-Ang损伤模型中的地震损伤指数概念,采用HAZUS方法的理论框架,提出基于地震损伤指数的地震人员伤亡预测方法.通过对某6层钢筋混凝土框架进行地震人员伤亡分析,表明提出的方法在地震人员伤亡预测中的科学性和可行性.

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.
