摘要:
研究组装式钢货架焊接式柱脚节点,分析此种节点绕立柱截面对称轴的抗弯性能,以及轴力对节点抗弯性能的影响.试验中节点的主要变形为底板扭曲,在立柱转角较大时,立柱角部附近腹板的焊缝被撕裂. 结果表明, 立柱中的轴力可增加节点的初始刚度和极限弯矩. 有限元模拟结果与试验结果吻合较好.通过对比参数发现,立柱轴力对柱脚节点初始刚度的增强效果会随着轴力的增大而减弱;轴力较大的试件具有较长的节点弯矩-转角曲线弹性段;增加立柱底板厚度可有效提高柱脚节点的刚度和抗弯承载力.
Abstract:
The tests of column base connections in assembled storage racks were carried out to investigate the bending behavior of the connections rotating around the column section’s symmetry axis. The effect of column axial force on the bending property of connections was taken into consideration. The main deformation of tested connections was the distortion of the baseplate and the tear at the column corner weld. Tests indicate that the column axial force is a positive factor for initial stiffness and ultimate moment of connections. These connection tests are numerically simulated using the finite element method, and the test results demonstrate the reliability of the simulation. The conclusions obtained by parameter comparisons include: ① The increase of the column axial force is able to enhance the initial stiffness of connection. ② The connection with a larger column axial force has a longer elastic stage in moment-rotation curves. ③ The increase of baseplate thickness is also an efficient method for heightening the stiffness and bending capacity of column base connections.
