摘　　要：介绍了双向贯通式节点在轴拉 (压 )、弯扭作用下的足尺节点试验研究。试验结果表明 ,该节点有明显的应力集中现象 ,应在强度设计中留有余地。通过对不同构造节点的有限元分析可知 ,增加节点域板件厚度是提高节点力学性能的有效方法。The full\|scale model tests of unstiffened steel tubular X\|joint under axial force,bending and torsion conditions are presented in the paper. The test results show that the X\|joint has distinctly stress concentration,which should be considered seriously in design.Finite element analysis indicates that increasing the thickness of plates of the X\|joint is the effective method to improve the mechanic behavior of the unstiffened steel tubular X\|joint.
