摘要
为了分析“下托上拉”式连接节点对于墙板在大变形情况下的保护作用,本研究通过Abaqus有限元软件建立了预制带肋复合墙板模型及节点模型,模拟计算节点受到荷载及墙板位移作用时的动力特性,分析节点的应力、位移变化。同时通过振动台试验验证模拟计算结果的合理性。结论表明,模拟计算与试验结果的贴合度较好。节点反力-位移曲线随着墙板位移方向的不同而不同,节点的破坏位置与形式也存在差别,表明“下托上拉”式连接节点具备协同变形能力,能够有效协调墙板-钢梁间的应力分布及结构变形,发挥半刚性节点保护墙板的作用。
In order to analyze the protective effect of the“push-up”type joint on the wall panel under large deformation,the research established the prefabricated composite wall panel model and the node model by Abaqus finite element software,simulated the dynamic characteristics of the node under the load and the displacement of the wall panel,and analyzed the changes of the stress and displacement of the node.At the same time,the rationality of the simulation results is verified by shaking table test.The results show that the simulation results are in good agreement with the experimental results.The reaction-displacement curve of the joint varies with the displacement direction of the wall plate,and the failure position and form of the joint are also different.This indicates that the joint of the lower bracket and the upper pull type has the ability of cooperative deformation,which can effectively coordinate the stress distribution and structural deformation between the wall plate and steel beam,and play the role of the semi-rigid joint to protect the wall plate.
