Pressed diagonal web member riveting joint equivalent structure
The invention discloses a pressed diagonal web member riveting joint equivalent structure, and relates to the technical field of steel truss girder bridges. The pressed diagonal web member riveting joint equivalent structure comprises an upper equivalent section, a lower equivalent section and two local joint plates, and the two sides of the upper equivalent section and the two sides of the lowerequivalent section are each covered with one local joint plate; and a plurality of full-scale rivets are arranged at the coinciding positions of each local node plate and the upper equivalent sectionand the coinciding positions of each local node plate and the lower equivalent section, and the lower edges of the local node plates are fixedly connected with the lower equivalent section through fillet welds. The pressed diagonal web member riveting joint equivalent structure can effectively simulate the stress condition of a joint local structure prototype, and the damage form of the joint local structure prototype is basically not affected. Meanwhile, the upper equivalent section and the lower equivalent section facilitate loading of the equivalent structure of the riveted joint of the pressed diagonal web member, test research can be carried out by utilizing universal test equipment, customization of a set of particularly large multi-point loading test device is avoided, and the testcost is greatly saved.
本发明公开了一种受压斜腹杆铆接节点等效结构，涉及钢桁梁桥技术领域，包括上等效节段、下等效节段和两个局部节点板，所述上等效节段和所述下等效节段的两侧均盖设一所述局部节点板，各所述局部节点板与所述上等效节段和所述下等效节段的重合处均设置有若干足尺铆钉，所述局部节点板的下边缘与所述下等效节段通过角焊缝固定连接。本发明的受压斜腹杆铆接节点等效结构能有效模拟节点局部结构原型的受力情况，其破坏形式基本不受影响。同时，上等效节段和下等效节段便于对受压斜腹杆铆接节点等效结构进行加载，可以利用通用的试验设备开展试验研究，避免了定制一套特别大型的多点加载试验装置，大幅节约了试验成本。
