| 摘 要： | 为改善普通低剪力墙的抗震性能,本文提出了一种新型延性低剪力墙方案:带水平短缝墙,通过低周反复荷载试验,对这种延性墙的性能进行了研究,结果较为理想。根据试验结果,提出了不同类型低剪力墙的恢复力模型,并用此模型编制了非线性动力反应程序,用直接输入地震波的方法,计算分析了它们不同的动力、耗能反应,并由此对不同类型低剪力墙性能予以评价。计算结果表明,带水平短缝墙具有良好的抗震性能。

| Abstract: | A new type of ductile lowrise shearwall with many short horizontal keyways is introduced in this paper in order to improve the earthquake resistant behavior of ordinary lowrise shearwall. The behavior of this wall is stuided through low-frequency cyclic loading experiment. The results are satisfactory. Based on the test results, the paper puts forward the different restoring force models for different lowrise shearwalls. A program for their nonlinear dynamic analysis is worked out by adopting these models. Through directly inputting earthquake waves, the paper analyses the dynamic response and energy dissipation of 3 types of lowrise shearwall, from that, the evaluation of earthquake resistant capacity is given. The calculation results demonstrate that the newly devised ductile shearwall has better earthquake resistant behavior. |
