摘要
在试验的基础上,采用有限元软件ANSYS对低周往复荷载下的N型圆钢管相贯节点进行滞回性能分析,揭示了该节点具有良好的塑性变形能力.将计算结果与试验结果进行对比,验证了有限元模拟往复试验的可行性,为N型圆钢管相贯节点在实际工程中的应用提供了参考依据.
On the base of experimentation, hysteretic behavior of unstiffened tubular N-joint under cyclic load is researched by ANSYS, a finite element software, and it reveals that the unstiffened tubular N-joint is possessed of well capability of plastic deformation.The research makes a comparison between finite element method and tested results, and validates that it is feasible to take finite element method to simulate experiment, which offers some valuable reference to the application of unstiffened tubular N-joints for actual projects.
