【摘要】 为修正广东省标准《建筑工程混凝土结构抗震性能设计规程》（DBJ/T 15-151-2019）中型钢混凝土（SRC）剪力墙的变形性能指标体系，根据我国现行规范，设计了12个一字型SRC剪力墙试件进行低周往复试验，对其破坏形态、耗能能力、变形能力、位移延性等进行研究。根据试验结果，提出基于骨架曲线的性能状态划分方法和基于破坏现象的性能状态划分方法，两种方法确定的变形性能指标限值吻合且可相互表征，由此建立构件变形—构件损坏程度—构件承载力的对应关系；基于该研究12个试件和文献收集的92个试件共104个试件的低周往复试验结果，修正了SRC剪力墙的破坏形态判别准则，建立了SRC剪力墙关键性能点θ1、θ5、θ6的回归公式。最后，基于ASCE/SEI 41-13对建立的关键性能点回归公式进行超越概率调整，修正了SRC剪力墙的变形性能指标限值。更多还原

【Abstract】 In order to revise the deformation performance index system of steel reinforced concrete（SRC） shear walls of Guangdong provincial standard Specification for Performance-based Seismic Design of Reinforced Concrete Building Structure（DBJ/T 15-151-2019）, 12 steel reinforced concrete（SRC） shear walls were designed and tested under low-cyclic loading based on current standard. Seismic behaviors, such as failure pattern, energy dissipation capacity, deformation capacity and displacement ductility were investigated.According to the test results, two performance state division methods based on skeleton curve and failure phenomena were proposed respectively and a comparison between the two methods was made. The deformation performance index limits obtained by these two methods were consistent and could be characterized each other, which verified the rationality of the performance state division method based on skeleton curves. Based on this, the relationship among deformation, extent of damage and bearing capacity of the component was established.Based on the low-cyclic loading test results of 104 specimens, including 12 specimens in this paper and 92 specimens collected from literature, failure mode classification was revised and the regression formulas for the key performance points（θ₁, θ₅, θ₆） of SRC shear wall were established. Finally, the established regression formulas for the key performance points were adjusted by exceedance probability based on ASCE/SEI 41-13, and the deformation performance index limits of SRC shear walls were revised.更多还原
