采用ABAQUS对钢梁-混凝土墙全螺栓半刚性连接节点进行分析研究,结果表明,钢梁-混凝土墙全螺栓连接节点滞回曲线饱满,具有较好的耗能能力;节点的初始刚度和抗弯承载力随着角钢厚度、钢梁高度、抗滑移系数的增大而增大,随轴向力、螺栓孔中心到角钢长肢边的距离增大而减小。采用正交回归分析得到节点初始刚度与抗弯承载力公式。
ABAQUS is used to analyze the semi-rigid connection of steel and concrete wall bolting. The results show that the full hysteretic curve of the full bolted joint of steel beam and concrete wall is full and has good energy dissipation capacity. The initial stiffness and bending resistance of the joint The bearing capacity increases with the thickness of the angle steel, the height of the steel beam and the anti-slip coefficient, and decreases with the increase of the axial force and the distance from the center of the bolt hole to the long limbs of the angle steel. The initial stiffness and flexural capacity formula of the joint are obtained by orthogonal regression analysis.
