建筑施工套式钢管支架钢管立杆套式节点剪切性能试验研究

Experimental Study on the Shear Distribution of Steel Pole Node for Steel Tubular Formwork Support with Couplers in Building Construction

通过对钢管立杆套式节点进行试验,获得几种加载类型剪切试验的节点最终破坏形式,双剪对称试验为钢管局部屈曲;单剪对称试验为对称两套环剪切破坏或点焊缝处焊缝撕裂破坏;单剪非对称试验为非对称两套环剪切破坏或点焊缝处焊缝撕裂破坏。

Based on the test of steel pole nodes,the results show that the local buckling of steel tubes will cause failure under the symmetrical double shear loads; the shear failure of symmetrical ringers or welds will cause failure under the symmetrical single shear loads,the shear failure of dissymmetrical fingers or welds will cause failure under the dissymmetrical single shear loads.
