| 摘 要： | 收集了68片国内钢筋混凝土悬臂剪力墙低周反复水平荷载的试验结果,对剪力墙各位移角进行了统计分析。根据统计结果,得出悬臂剪力墙开裂、屈服和极限位移角与轴压比、配箍特征值、边缘构件约束长度之间的线性回归关系。认为当量化以开裂为标志的位移性能目标时,应着重考虑配箍特征值和边缘构件约束的影响;当量化以屈服为标志的位移性能目标时,应着重考虑轴压比的影响。并在此基础上提出了可供参考的各性能水准下的层间位移角限值。

| Abstract: | Based on the collected test results of 68 domestic reinforced concrete shear walls under low frequency and reserved lateral loads,various displacement angles are counted.The relations of various displacement angles to axial-load ratio,the stirrup characteristic value and the length of the edge are regressed.And quantitative to cracking,yield represented the displacement performance objectives should focus on the different influencing factors.The different quantitative criteria for allowable value of drift angle are proposed. |
