砌体和钢混结构建筑群的破坏概率模型研究

通过对已有震害预测的易损性矩阵进行研究，对目前易损性矩阵的概率模型进行了修改。分析了华南地区建筑群的3种主要结构类型:钢混结构，砖混结构和砖木结构。将3种结构在各种烈度下的破坏状态分别进行了拟合和参数计算，针对其差异性提出了偏态分布和正态分布，给出了不同的破坏概率模型。在广东省惠州市数据的验算下，证明了对于砌体和钢混建筑群易损性矩阵的呈现有一定的参考意义。

Research on seism damage probabilistic model for masonry and steel-concrete structure building group

By studying the existing vulnerability matrix of earthquake damage prediction, the probability model of current vulnerability matrix was modified. Three main structure types in south China were analyzed in this paper including steel-concrete structure, brick-concrete structure and brick-wood structure, whose damage states were fitted and parameter were calculated under different intensity. According to their difference, the skewed distribution and normal distribution were proposed, and different damage probability model are presented. based on the results of checking the data of Huizhou city, Guangdong province, this paper has certain reference significance for the presentation of the vulnerability matrix of masonry and steel-concrete buildings.
