【摘要】 主要讨论了地震潜在风险的计算方法。根据水平向地震加速度超越概率曲线,通过曲线拟合得到曲线的表达形式,从而获得地震加速度的概率密度函数;通过建筑结构的以易损性指数表达的易损性矩阵及多个城市的数据处理,得到建筑结构破坏程度即易损性指数的概率密度函数;最后通过上述的地震危险性分析和建筑结构的易损性分析就可以评估地震潜在风险。更多还原

【Abstract】 The calculating method of potential risk of earthquake is proposed in the text.With the exceeding probability curve of seismic acceleration,the expression of the curve can be obtained by curve fitting method,and also the probability density function of the seismic acceleration is obtained.By vulnerability matrix of structures which is expressed by damage index and data processing of multiple cities,the damage probability of the structures at specific level can be gained under specific seismic acceleration.Potential risk of earthquakes could be evaluated by SHA(seismic hazard analysis) and SVA(structural vulnerability analysis).更多还原
