摘要
现有钢结构节点设计手册未给出梁端加强式方钢管柱与H型钢梁刚性节点(HSS-H刚性节点)极限承载力的计算公式。运用大型通用有限元分析软件ANSYS对HSS-H刚性连接节点的极限承载力研究,通过平衡路径应力分布图进行结果比较和分析,表明了通过梁端加盖板和肋的方式加强梁柱节点能有效地迫使梁端塑性铰向梁的跨中移动。
Current connection design guides do not present the calculation of ultimate load - bearing capacity of Hollow - Section - Steel column and H - Section beam rigid connections stiffened at the end of beam （HSS- H rigid connections）. The ultimate load - bearing capacity of HSS - H rigid connections is was analyzed by using finite element software ANSYS. The comparative calculation of stress distribution on equilibrium path shows that the cover and rib stiffeners force the plastic hinger zone at the end of beam to move forward to mid - span of the beam efficiently.
