半刚性节点由于其优越的受力性能,得到国内外研究者的广泛关注。提出一种采用角钢连接的方钢管混凝土柱和钢梁的新型半刚性节点形式,并通过与欧洲规范EC 3对比,确定新型节点属于半刚性连接。提取节点螺栓群在不同参数下的剪力和弯矩,分析节点在荷载作用下承担弯矩和剪力的主要机制。通过分析,给出连接板处螺栓承担节点竖向剪力的百分比,以及角钢连接处螺栓承担弯矩的百分比。
Due to its superior mechanical properties, semi-rigid joints have drawn wide attention from researchers at home and abroad. A new type of semi-rigid joint with square steel tube concrete columns and steel beams connected by angle steel is proposed and compared with European standard EC 3, it is determined that the new type of joint belongs to semi-rigid connection. The shear stress and bending moment under different parameters of the bolt group are extracted, and the main mechanism of bearing moment and shear under load is analyzed. Through the analysis, the percentage of the vertical shear force of the bolt at the joint plate and the moment at the joint of the angle steel are given.
