【摘要】 本文对联肢钢板剪力墙的滞回性能展开了研究,利用ABAQUS进行了有限元分析,研究了柱轴力与耦连比的关系,以及耦连比、连梁截面尺寸和墙板厚度对联肢钢板剪力墙结构承载力、延性、刚度退化、耗能能力及破坏模式等方面的影响。研究表明,框架边柱与内柱的轴力会随着耦连比的增大而接近,当耦连比在0.4～0.6之间时,连梁与墙板可发生充分的剪切屈服,边柱的柱端塑性铰最后出现,诱发结构破坏。钢连梁能够很好的参与结构耗能,将"钢板剪力墙-框架"抗侧力体系改进为了"钢板剪力墙-钢连梁-框架"抗侧力体系。更多还原

【Abstract】 In this paper, the hysteretic performance of the coupled steel plate shear wall is studied. Using the ABAQUS finite element simulation, the relationship between the column axial force and the degree of coupling was studied. And the influence of the cross-section size of the connecting beam and the thickness of the wall plate on the bearing capacity, ductility, stiffness degradation, energy dissipation capacity and failure mode of the coupled steel plate shear wall structure were studied. The research shows that the axial force of the frame side column and the inner column will approach with the increase of the coupling ratio. When the coupling ratio is between 0.4-0.6, the coupling beam and the wall panel can produce sufficient shear yield. The plastic hinge at the end of the column finally appeared, causing structural damage. Steel coupling beams can participate in the energy dissipation of the structure well, and the "steel plate shear wall-frame" anti-lateral force system has been improved to the "steel plate shear wall-steel coupling beam-frame" anti-side force system.更多还原
