3) injured degree
受害等级
4) earthquake damage grade
震害等级
1.
Thus the tradition step distribution way of structure vulnerability,which is expressed by intensity versus earthquake damage grade is converted to continuous distribution way expressed by seismic ground motion parameter compared to destruction ratio.
用贝塔分布函数对给定烈度下结构各个破坏等级的概率分布进行了破坏比概率密度的拟合,以地震动峰值作为地震动参数,根据烈度和加速度峰值的对应关系以对数插值方式计算了在任意一个峰值加速度下结构破坏比的倍塔概率密度分布及各个破坏等级的概率,从而使结构易损性的表达方式由烈度-震害等级构成的二维阶跃性易损性矩阵转化为由地震动参数-破坏比概率密度函数或地震动参数-各破坏等级的概率来表达的方式。
