【摘要】 目前我国通常采用的地震危险性分析方法是基于地震的发生属于泊松模型,但实际上地震发生的特点与泊松模型的假设有一定差异。本文根据实际地震发生的特点,总结出地震发生的双态泊松模型,把地震活动期分为相对平静期和相对活动期,并且这两个活动期分别符合泊松模型。在此基础上,对地震危险性的分析方法进行了探讨。更多还原

【Abstract】 As a fact is that 86 percent of the earthquakes occurred in China have successive strong quakes, most structures were severe damaged by the successive earthquakes. How to evaluate the aseismic capability of the preliminary damaged buildings became a big problem for the rehabilitation works after the first strike. A comprehensive method was presented in this paper. First, the structural earthquake prevention capability was evaluated by the traditional methods. Second, the damage suffered in the first quake was introduced as a reduction factor for the results of the first step. Third, the predicted earthquake action was applied for the structures to evaluated the damage of the buildings.更多还原
