摘　　要：建筑物震害预测对于制定城市防震减灾规划意义重大,对于我国高烈度区建造的砖墙-钢筋混凝土剪力墙组合结构,目前没有成熟的震害预测方法。为了预测西昌市砖墙-钢筋混凝土剪力墙组合结构建筑物在不同地震烈度下可能发生的震害程度,通过分析该种结构在不同地震作用下的受力特点,提出以结构薄弱层的楼层屈服强度系数为指标进行震害预测,并结合算例给出计算方法。Seismic damage prediction of buildings is significant for urban earthquake prevention and disaster mitigation planning.There is no mature seismic damage prediction method for the composite structures with brick walls and reinforced concrete walls,which appear in high design intensity areas.To predict the earthquake damage to composite structure buildings with brick walls and reinforced concrete walls in the city of Xichang,we proposed that according to the yield strength coefficient of the weakest floor,by analyzing the structure effect due to different seismic actions the seismic damage to this type of struetures can be predicted.Calculating method is put forward with engineering example.
