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 joint test of two-way through-going joints under axial tension (compression) and bending-torsion is introduced. The experimental results show that the node has obvious stress concentration phenomenon and should leave some room for strength design. Through the finite element analysis of different structural nodes, we can see that increasing the thickness of joint plate is an effective method to improve the mechanical properties of joints.
