摘要
本文在分析现有结构地震破坏模型的基础上，提出了一种改进的双参数地震破坏模型。文中采用三线退化型恢复力模型对实际钢筋混凝土结构在实际地震（唐山地震、海城地震、天津地震）作用下的变形与累积耗能、极限变形与极限滞回耗能进行了分析，通过模型计算的破损结果与实际震害结果的对比，确定了模型参数，从而建立了钢筋混凝土结构的双参数地震破坏模型．
In this paper,based on the current seismic damage models,a modified model with double variables is presented for reinforced concrete(R.C.)structures.By using a tri-linear restoring force model of structural members,the deformation,cumulative hysteretic dissipation energy, ultimate deformation and ultimate hysteretic dissipation energy are analyzed for real R.C.structures under real earthquakes(Tangshan,Haicheng and tianjin earthquakes). Then,by comparing the calculated seismic damage indexes with the real damage indexes of structures,the model parameters are determined and the model is established.
