摘　　要：对于轮扣式钢管支架的节点,开展了抗弯和抗剪的加载试验研究,获得了节点的破坏模式,刚度和承载力等力学响应,并与现有设计的方法计算结果开展了比较。比较结果表明现有设计规范的计算结果是偏安全的。Experimental investigation was performed on the wheel-coupler steel tubular scaffolding joints under bending and shear loading.Failure modes,stiffness and ultimate strength were obtained from the test results.Design predictions obtained from current standards were compared with the test results.It is shown that the design values are generally conservative.

关 键 词：轮扣式 钢管支架 节点
