| 摘 要： | 提出了一种通过构建具有普适性的概率模型对群体建筑物进行震害预测的方法。该方法基于已有的群体建筑物易损性矩阵,通过概率分析和数据拟合,进行构建建筑群的破坏概率模型,并通过计算建筑物易损性指数的均值和方差来确定其具体参数。分析表明,该概率模型对群体建筑物震害预测具有一定的可行性和普遍的适用性。

| Abstract: | A new method is proposed for seismic damage prediction of building group by deriving a probabilistic model.Based on the existing vulnerability matrix of buildings,the damage probabilistic model for building group is obtained by probabilistic analysis and data fitting.Then by calculating the mean and variance of vulnerability index,the parameters of the model can be firmed.This probabilistic model is widely applied to seismic damage prediction of building group. |
