【摘要】 运用结构响应等效的思想，对地震动模型进行了研究。在用Ｍｏｎｔｅ－Ｃａｒｌｏ法求取大量结构在众值烈度作用下弹性时程分析的响应统计特性的基础上，将地震地面运动等效成了形式简单的简谐激励模型，同时在频域上为随机地震模型———Ｋａｎａｉ模型确定了有明确意义的模型参数。更多还原

【Abstract】 n this paper,studies on models of earthquake ground motion are carried out with the idea of the equivalent of aseismic structure’s response. On the base of structures’ response characteristics acquired by a number of structure time history analyses with Monte-Carlo method under excitations of frequent intensity,the earthquake ground motion is modeled as the sinusoidal model, while in the frequency domain, parameters of the stochastic earthquake model, Kanai model, are evaluated. 更多还原
