矩形管状构件端板与底板螺栓连接节点的性能

研究矩形空心截面外伸端板接头的屈服机制,认为螺栓位于端板的角部。现有规范没有针对钢结构和铝合金结构中的这类连接节点给出相应的设计准则。采用欧洲规范中的对称分量法研究考虑和不考虑撬力作用下新屈服机制的可靠性,基于试验结果建议采用新屈服机制。

End and Base Plate Joints with Corner Bolts for Rectangular Tubular Member

This paper considers yield mechanisms for extended end plate joints of rectangular hollow sections. In this paper bolts are considered which are located at the corners of the end plate. In present codes no specific design rules for these kinds of joints in steel and aluminum structures are given. The purpose is to study the reliability of the new yield mechanisms for the component method of the Eurocodes, both for cases with and without prying forces. Proposals for the use of new yield mechanisms are based on tests available in literature.
