提出了一种适用于H形柱的箱形节点域外伸端板弱轴连接,利用有限元软件ABAQUS对8个不同构造形式的端板连接进行了研究,分析了节点的破坏形式、弯矩转角滞回曲线、承载能力及转动能力等。结果表明:8个不同构造形式的端板连接均为半刚性节点;在循环荷载作用下,箱形节点域端板连接节点的破坏均出现在端板上,而柱子节点域基本完好;当层间位移角为0.04 rad时,各节点的承载力均大于0.8倍钢梁全截面塑性弯矩;端板外伸加劲肋的设置使节点的极限承载力提高10%左右,但耗能能力却下降了4%,建议外伸端板不另设加劲肋;端板厚度为16 mm,即与蒙皮板厚度相差较小时,节点的承载能力、耗能能力较好;提升端板材性能提高节点承载能力,但端板材性提升过大反而会降低节点耗能能力,建议端板材性只提高1个等级。

A new box node domain extended endplate weak axis connection suitable for H-section connection was put forward, eight different models of the end-plate connection were studied by finite element software ABAQUS. The failure mode of node, the moment-rotation curve, ultimate bearing capacity and energy dissipation capacity were analyzed. The results show that the eight models are semi-rigid nodes; under cyclic loading, the failures of the box node domain endplate connections are present in the end-plate, and the column is substantially in elastic state; when the story drift angle is 0.04 rad, the respective bearing capacities of the nodes are higher than 0.8 times of whole section plastic moment; although the ultimate bearing capacity of the end plate with extended stiffener has increased about 10%, the energy dissipation capacity has decreased 4%, so extended endplate stiffener is not provided; when the end-plate thickness is 16 mm, that is, the thickness difference between the end-plate and the skin plate is small, the bearing capacity and energy dissipation capacity of nodes are better; enhancing the properties of end plate can improve the load carrying capacity, but the node energy dissipation capacity will reduce if end-plate properties are increased too more, so it is recommended that the properties of end-plate are increased only one grade.
