摘　　要：我国现行抗震规范(GB 50011-2010)没有给出型钢高强混凝土结构基于性能设计的量化指标,无法评估其在不同地震设防水准下的性能状态,故有必要对其变形性能指标进行研究。本文首先将结构性能水准划分为正常使用、暂时使用、修复后使用、生命安全和防止倒塌五档性能水平,给出了对应的破坏状态,确定结构性能水平失效判别标准。在总结126组试验数据基础上,提出了型钢高强混凝土柱五档性能水平对应的层间位移角限值。Chinese Code for Seismic Design of Buildings（ GB 50011-2010） has no explicit performance index limit values of steel reinforced high-strength concrete structure for performance-based seismic design method,resulting in the impossibility of evaluating its performance under different seismic fortification levels. As a result,it is necessary to quantify the performance index of steel reinforced high-strength concrete structure. in this paper,the seismic performance of steel reinforced high-strength concrete structure is divided into five levels of normal service,temporary service,repairable service,life safety and collapse prevention,and the corresponding failure state is also given. The judging criterion for performance failure is determined. in summing up the seismic experiment study of steel reinforced high-strength concrete columns,the story drift angle limit values are proposed corresponding to different seismic performance levels.
