摘　　要：对建筑物灾变发生时经济损失和人员伤亡情况做出准确预估是未来建筑结构设计初期需要努力的方向。基于下一代性能化设计理论,通过精细化建模和动力时程分析对结构进行易损性分析,并以此得到抗震性能评估所需的各类地震响应参数,建立RC框架结构全概率抗震性能评估方法。以云南大学力行楼为例,通过地震损失预测得到了该栋建筑的经济损失、修复时间和人员伤亡情况。该方法直观清晰地展示了结果,便于业主及非本专业从业者理解。The accurate prediction of economic losses and casualties in an event of building catastrophe is the direction that needs to be worked out in the early stage of future structural design.In this paper,based on the next generation performance-based design theory,the fragility of RC frame structures is analyzed by refined modeling and dynamic time-history analysis,and various seismic response parameters for seismic performance evaluation are obtained.The total probability seismic performance evaluation method for RC frame structures is established.Using the Lixing Building in Yunnan University as an example,the economic loss,repair time and casualties of the building are obtained by earthquake loss prediction.This method shows the results visually and clearly,which is easy to understand for owners and non-professional practitioners.
