基于被动控制的设计概念,该文在开缝剪力墙的基础上,在缝槽中填入粘弹性材料,并将这种构件应用到一幢八层钢筋混凝土剪力墙结构中。基于通用有限元软件ABAQUS,建立了该结构的弹塑性有限元模型,并对其在地震下的性能进行了数值模拟,重点研究了墙体开缝对结构地震反应的影响,以及缝槽中填充粘弹性材料对结构的控制作用。研究结果表明,墙体开缝降低了结构的刚度,增大了结构的位移反应,但开缝对减小结构底部反应及改变结构损伤分布有利。而缝中填充粘弹性材料后,可有效的控制结构的地震反应,减小结构的损伤,具有良好的实际应用意义。
Based on the design concept of passive control, this paper, based on the slitted shear wall, filled the slot with viscoelastic material and applied it to an eight-story reinforced concrete shear wall structure. Based on the general finite element software ABAQUS, the elasto-plastic finite element model of the structure is established and its performance under earthquake is numerically simulated. The influence of the wall crack on the seismic response of the structure is studied emphatically. Viscoelastic materials control the structure. The results show that the slits of the wall reduce the stiffness of the structure and increase the displacement response of the structure, but the slits are beneficial to reduce the bottom reaction of the structure and to change the damage distribution of the structure. The viscoelastic material filled in the seam can effectively control the seismic response of the structure and reduce the structural damage, which has a good practical significance.
