【摘要】 通过对2.8 m×2.4 m （高×宽）轻钢密肋龙骨墙体足尺试件水平加载试验，分析墙体受力过程和破坏模式；对墙体抗剪承载力进行研究。试验结果表明：所研究墙体屈服始于下导轨的抗拔件位置，最终破坏是由于墙体立柱与下导轨焊缝被拉断或下导轨焊缝附近金属撕裂破坏。利用ABAQUS对龙骨墙体进行有限元模拟及参数分析，模拟结果表明：撑杆间距加密的纯龙骨墙体抗剪承载力有所增加，而其抗侧刚度明显有所提高；随着立柱的截面宽度以及立柱截面的壁厚增加，纯龙骨墙体的抗剪承载力及刚度也有所增加。更多还原

【Abstract】 Through the horizontal loading test of 2.8 m×2.4 m(height×width) keel of light gauge steel combination wall specimens, the process and failure modes of the keel were analyzed; the shear capacity of the wall was studied. The results show that the combination of the wall with the resistant piece at the lower rail yields first. The final damage is caused by the tensile fracture of the wall column and the lower rail weld or the metal torn near the lower rail weld. Using ABAQUS, The simulation results show that the shear bearing capacity of the pure keel wall encrypted by spacer spacing increases, but the increase of bearing capacity is smaller; the larger the cross-section dimension of the pillar and the thickness of the pillar cross section, the greater the shear bearing capacity and rigidity of the pure keel wall.更多还原
