石河子市多层砖混结构房屋震害概率矩阵的建立

ESTABLISHMENT OF EARTHQUAKE HAZARD PROBABILITY MATRIX OF MULTI-STOREY BRICK-CONCRETEBUILDINGS IN SHIHEZI CITY,XINJIANG

以概率理论为基础 ,采用震害指数法对石河子市重要建筑物中的多层砖混结构房屋进行抗力计算 ,通过抽样计算建立了石河子市砖混结构房屋按建筑年代分类的震害概率矩阵 ,又进一步综合这次普查得到的相关统计数据建立了修正的石河子市砖混结构房屋震害概率矩阵 。

The earthquake hazard index of key multi-storey brick-concrete-frame buildings in Shihezi City,Xinjiang was calculated based on probability theory. The brick-concrete-frame buildings in Shihezi city were classified according to their built age. Every class of earthquake hazard probability matrix was given through sampling calculation,and the modified earthquake hazard probability matrix of the buildings in Shihezi city was given on the basis of comprehensive information from general survey,thus providing the base for seismic hazard prediction of buildings.
