摘要
文章基于4个空间角钢骨架加强节点低周反复荷载试验,分析了空间角钢骨架加强节点的裂缝开展、剪切变形和节点转动机理,从中发现空间角钢骨架对节点开裂方式的本质影响,从而提出了节点开裂剪力计算方法,并将理论计算结果与实际值进行比较分析,得出了空间角钢骨架对节点抗剪性能的影响,给出了节点抗剪承载力设计建议公式。
On the basis of the short-cycle loading test of the four knots strengthened by the dimensional angle-iron framework, this paper deals with the crack way,shear deformation and rotation of the knots. The effect of the dimensional angle-iron framework on the crack way in essence is found out, the method to calculate the crack shear force is brought forward,and the theoretical results are compared with the measured results. The effect of the dimensional angle-iron framework on the shear-force behavior of the knot is analyzed. The formula to calculate the shear-force capability of such knots is presented.
