钢筋混凝土带缝剪力墙体系是近年来出现的一种新型抗震结构体系。已有一些理论和试验研究对隔震连梁和带缝剪力墙模型在静力荷载作用下的行为进行了研究，但很少有人对结构体系的动力行为进行研究。本文分析了带缝剪力墙在地震作用下的非线性地震反应。基于一个简化的结构模型，这被证明是有足够的精度为缝剪力墙结构，连接梁的弹塑性行为的影响缝剪力墙结构的动力响应进行了评估。研究结果表明，连梁的屈服能显著降低带缝剪力墙结构的挠度反应和地震荷载，且连梁的屈服强度存在一个最佳值，使带缝剪力墙结构的整体抗震性能最佳.
The reinforced concrete slit shear wall system has been introduced recently as a new breed of earthquake resistant structures. Some theoretical and experimental investigations have been conducted to study the behaviour of isolated connecting beams and slit shear wall models under static load, but little work has been carried out to investigate the dynamic behaviour of the structural system. In this paper, the non-linear seismic response of slit shear walls under earthquake excitation is analyzed. Based on a simplified structural model, which is shown to have sufficient accuracy for slit shear wall structures, the influence of the elasto-plastic behaviour of the connecting beams on the dynamic response of the slit shear wall structure is evaluated. The results reveal that yielding of the connecting beams can significantly reduce the deflection response of the slit shear wall structure and the seismic loading induced on it. Moreover, there appears to be an optimum yield strength value for the connecting beams that would lead to the best overall seismic performance of the slit shear wall system.
