Earthquake excitation is represented by random process and structural damage is assessed in terms of maximum displacement and accumulated energy dissipation.
地震扰动用随机过程表示,结构的破坏用最大位移和累积能量耗损两个参数来评定。
This model is represented in terms of a "damage index" which is a nonlinear function of maximum deformation and accumulated energy dissipation, and follows Weibull distribution.
此模型由一“破坏指标”表示,它是最大变形和累积能量耗损两个参数的非线性函数,其统计特性服从威布尔分布。
