全栓接H型钢梁柱节点有限元与试验对比分析
|
摘要
利用ABAQUS软件对4种不同构件梁柱节点进行了非线性有限元分析,获得了连接节点在循环荷载作用下的破坏模式、M-θ骨架曲线以及主要力学性能参数,并与试验结果进行了对比。结果表明:ABAQUS模拟所得结果与试验结果吻合较好,ABAQUS能够较为准确地模拟半刚性节点的受力性能;全栓接H型钢梁柱采用不同种类T型件连接是合理可靠的;相较于传统节点,全栓接新型节点在弱轴方向上的承载力和延性均有显著提高,表现出更优越的力学性能;有限元分析与试验研究对比分析的正确可靠性,进一步验证了设计构件的合理可行性。
The nonlinear finite element analysis of four different beam-column joints was performed by ABAQUS software.The failure mode,M-θ skeleton curve and main mechanical properties of the joint under cyclic loading were obtained and compared with the experimental results.The results show that the results of ABAQUS simulation are in good agreement with the experimental results.ABAQUS can accurately simulate the mechanical behavior of semi-rigid joints.It is reasonable and reliable to completely bolt H-shaped steel beams and columns using different types of T-pieces.In the traditional node,the fully bolted new node has significantly improved bearing capacity and ductility in the direction of the weak axis,showing superior mechanical properties.The correct reliability of the comparative analysis between the finite element analysis and the experimental study further validates the reasonable feasibility of the designed components.
