| 摘 要： | 考虑了节点板厚度、抗剪键、加载模式的影响,对14个铝合金板式节点的承载力性能进行试验分析.详细介绍了试验过程,描述了试验现象.试验结果表明,铝合金板式节点的主要破坏模式为块状拉剪破坏和节点板局部屈曲破坏;以弯矩为主要控制的荷载作用下,节点板主要承受环向应力;节点板厚度的增加能有效提高节点承载力;C类抗剪键能显著提高节点的整体性,改善节点受力性能.

| Abstract: | Considering the influence of thickness of joint plate, shear connector and loading scheme on the load-bearing behavior of aluminum alloy gusset joint, experiments including 14 aluminum alloy gusset joint specimens were carried out. Firstly, the experimental program is introduced in detail. Subsequently, the collapse phenomena of joint specimens are described. It is found from the experimental results that: (1) their failure modes mainly involve the block shear rupture of the top plate and the local buckling of the bottom plate; (2) the joint plate is mainly subjected to hoop stress when the joint is under primary bending moment; (3) the increase of thickness of joint plate could enhance the load-bearing capacity of joint effectively; (4) the shear connector C could improve the global behavior of joint efficiently. |
