| 摘 要： | 在轻型钢结构建筑中采用的以单面角焊缝连接翼缘和腹板的组合H形截面钢构件 ,其焊缝接头性能尚未得到充分的试验验证。为此进行了两个基础性系列试验 :对单面角焊缝接头的 5 7个试件通过金相分析测定熔深 ,对 2 6个试件进行焊缝抗剪试验。试验结果表明 ,在单调静力荷载条件下 ,单面连接角焊缝有良好的承载和变形性能 ,可以按照钢结构设计规范有关规定计算其设计承载力。

| Abstract: | The properties of the joints with one side fillet weld connecting the webs to flanges in H shaped steel members used in light weight steel structures, have not been yet thoroughly researched by tests. Two basic experiments are reported. The deepness of the weld root was measured by metallographic examination on 57 pieces of samples, and the other 26 specimens where the welds were subjected to shear forces are loaded. The results show that the joints with one side fillet weld have sufficient loading capacity and deformablility to shear force under monotonic loading conditions, and the resistance of the weld can be calculated by the provisions of the present design specification of the steel structures. |
