摘要
采用ANSYS有限元分析软件,比较分析翼缘加强型狗骨式节点、狗骨式节点、扩翼式节点和普通刚性节点4种模型在单调荷载作用下关键部位的应力分布情况.结果表明:翼缘加强型狗骨式节点和狗骨式节点塑性铰外移效果显著,而且不需加大柱的截面;而翼缘加强型狗骨式节点与狗骨式节点相比较可知,由于梁翼缘截面的扩大有效地减小了焊接接头的应力值,梁端焊缝负担得到缓解.
On analysis of stress distribution of key locations under monotonic loading about four joints, the flange reinforced dog-bone joints, dog-bone joints, wide flange joints and ordinary moment joints are compared through ANSYS FEA software. The results expose that the effect of shift-away of plastic hinge is significant in the flange reinforced dog-bone joints and dog-bone joints, and it doesn't need to increase the cross-section of column. For the flange reinforced dog-bone joint is compared with the dog-bone joint, it is proved that the expansion of flange of beam can effectively reduce the stress value in welded connection, and alleviate the burden of welds in beam end.
