| 摘 要： | 针对作者新近研制的一种抗震处自控结构带缝钢筋混凝土高剪力墙，本文计算分析了该结构的非线性地震反应．基于一个简化的计算模型，文中的分析集中于缝槽间连梁的非线性性能对整体结构地震动下表现的影响．计算表明，缝槽间连梁的屈服能大大减小结构的地震反应，而且选择合适的连梁屈服强度，可使带缝剪力墙结构的地震反应得到最佳控制．

| Abstract: | A reinforced concrete slit shear wall is a new breed of earthquake resistant structure recently proposed by the authors. In this paper, the seismic responses of the slit shear walls under the shake of earthquake excitation have been dealt with. Based on a simplified structural model, which is shown to have a sufficient accuracy for the real slit shear wall structure, the analysis focuses on the influence of nonlinear behavior of the connecting beams between the slits on the dynamic performance of the whole slit shear wall structure. It has been found that the yielding of connecting beams in a slit shear wall can provide significant improvement in reducing the structural responses, and by choosing an appropriate strength value for the connecting beams, it is possible to optimize the seismic response of the slit shear wall. |
