山东潍坊地区多层砖房震害预测

THE PREDICTION OF SEISMIC HAZARD OF MULTI-FLOOR BRICK BUILDINGS IN WEIFANG AREA OF SHANDONG PROVINCE

利用多层砌体房屋震害预测专家系统，对山东潍坊地区１８２栋多层砖房逐栋进行了单体房屋的震害预测。在此基础上，统计分析了该地区多层砖房的地震易损性特征，并进行了初步震害预测研究，给出了该类房屋的易损性矩阵、各破坏等级的损失参数矩阵和对应不同地震烈度的相对损失预测。

The seismic hazard prediction for single building of 182 multifloor bri ck buildings in Weifang area of Shandong Province has been made one by one by th e expert system of seismic hazard prediction for multi-floor brick buildings.Ba sed on this,the statistics and analysis have been made for the seismic vulnerabi lity characteristics of multi-floor brick buildings in the area and a prelimina ry study of seismic hazard prediction has been made.The vulnerability matrix,the loss parameter matrix of various damage grades and the relative loss prediction corresponding to different seismic intensities of this ikind of buildings are g iven,which has provided a scientific basis for further carrying out seismic haza rd prediction and taking countermeasure for earthquake prevention and hazard red uction.
