【摘要】 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。更多还原

【Abstract】 Based on the passive control design,the slit which is set up in the wall is filled with viscoelastic material.Then this kind of shear wall member is applied to an eight-story reinforced concrete shear wall structure.By the finite element software ABAQUS,the structural elastic-plastic finite element model is established and its seismic performance is simulated.The impact of slit in the wall and how the viscoelastic material in the slit to control the structure are studied.The results show that the slit reduces structural stiffness and increases the structural displacement response.But the slit is favorable to reducing the structural bottom response and changing the damage distribution.After filling viscoelastic material in slit,the structural seismic response can be controlled and structural damage is reduced.Thusly,this kind of shear wall member has a good sense of practical application.更多还原
