摘要:
为了研究方钢管混凝土柱钢梁半刚性节点的力学性能和影响因素，以方钢管混凝土柱钢梁半刚性节点为研究对象，采用数值模拟分析方法研究了节点角钢厚度、角钢短肢长肢比及螺栓直径等参数对该类节点受力性能的影响规律，并给出了节点初始转动刚度的建议公式。结果表明：角钢厚度的变化对节点初始刚度影响较小，但对节点的塑性刚度和承载力影响较大；角钢短肢长肢比在一定范围内对节点刚度和承载力影响较明显，超过范围后只对节点的承载力有较大影响；螺栓直径的变化对节点承载力和刚度有一定影响，但影响程度较小，可不作为主要的影响参数。
Abstract:
In order to study the mechanical properties and influencing factors of semi-rigid connections between concrete-filled square steel tubular column and steel beam, the concrete-filled square steel tubular column-steel beam semi-rigid connection was taken as research object. The influence laws of the parameters such as the angle steel thickness, short and long limb length ratio of angle steel, bolt diameter on the mechanical behavior of the joint were investigated by numerical simulation. The formula for the initial rotational stiffness of the connection was given. The results show that the change of the thickness of angle steel has little influence on the initial stiffness of the connection, but it has great influence on the plastic stiffness and the bearing capacity of the connection. The short and long limb length ratio of angle steel has obvious influence on the stiffness and bearing capacity of the connection within a certain range, and it only has great influence on the bearing capacity of the connection beyond the scope. The change of bolt diameter has some influence on the bearing capacity and stiffness of the connection, but the influence degree is small, and it is not the main parameter.
