摘要
本文结合我国地震设防水准，在国内外有关地震损伤大量研究结果的基础上，提出了钢筋混凝土结构地震损伤的“三水准”性能目标；其次，对于剪切型钢筋混凝土结构，提出了结构层间柱－压弯构件三线性恢复力模型参数确定和地震损伤计算方法；第三，提出了地震损伤直接验算和将地震损伤验算归结为变形验算的钢筋混凝土结构地震损伤性能设计方法；最后，通过设计例题说明了本文方法应用的可行性。
Based on large quantities of research results of seismic damage at home and abroad, athree-level performance objective of seismic damage of reinforced concrete structures is developedaccording to design earthquake levels regulated in Chinese seismic code. Then, for shear typereinforced concrete structures, the methods for the calculation of tri-linear restoring forcemodel parameters and seismic damage index of inter-story columns── compression－flexuremembers are presented. Thirdly, seismic damage performance-based design approaches of rein-forced concrete structures are presented,which include the directly checking approach of seismicdamage . and the indirectly checking approach through checking equivalent deformation.Finally, a design example shows that the design method presented in this paper is feasible.
