钢结构工程梁与柱刚性连接的构造形式

发布时间:2015-9-2 9:35:30 浏览次数:625




1:钢结构全栓节点,梁翼缘和腹板籍助T形连接件用高强度螺栓与柱翼缘连接,虽然安装比较方便,便节点刚性不如前两种连接形好,应用并不多。

 
2:钢结构梁与柱刚性连接时,应验算梁与柱的连接承载力——在弹性阶段验其连接强度,在弹塑性阶段验算其极限承载力,在梁翼缘的压力和拉力作用下,钢结构分别验算柱腹板的受压承载力和柱翼缘板的刚度,节点域的抗剪承载力。

3:全焊接节点,梁的上、下翼缘用坡口全熔透焊缝,腹板用角焊缝与柱翼缘连接,钢结构栓焊混合连接节点,即仅梁的上下翼缘用坡口全熔透焊缝与柱翼缘连接,腹板用高强度螺栓与柱翼缘上的剪力板连接,是目前多屋和高层钢结构梁与柱连接最常用的构造形式。



1: steel structure of the switch node, beam wing flange and web by tee fitting with high strength bolts and column flange connection, although the installation is more convenient, and the node rigid not as good as the first two kinds of connection form, the application is not much.

2: steel structure beam and column rigid connection, should check bearing capacity of beam and column connection, check the connection strength in the elastic stage, calculating the ultimate bearing capacity in elastic-plastic stage, under the influence of the stress and strain of beam wing edge, steel structure, calculation of the column web compression bearing capacity and rigidity of the column flange plate, the shear capacity of the node domain.

3: all welded node, beam of the upper and lower flange with groove full penetration weld, web use fillet weld and the column flange connection, the steel structure welding mixed connection nodes, namely only beam from top to bottom flange with groove full penetration welds and column flange connection, the web plate with high strength bolts on the shear plate and column flange connection, is one of the many homes and high-rise steel structure beam and column connection structure form of the most commonly used.
