摘　　要：报告了 1 2个试件的抗剪极限承载力试验。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 ,对H形截面钢构件腹板剪切失稳后的极限承载力的不利影响很小 ,可以按照钢结构设计规范有关规定计算腹板抗剪极限承载力。Experimental researches on ultimate resistance against shear loads acting on 12 specimens are reported.The results show that the web-to-flange joints with one-side fillet weld have sufficient loading capacity and deformability under monotonic loading conditions.No obvious effect weakening the post-buckling shear strength of the H-shaped steel members due to one-side fillet weld was observed during the tests.The shear strength of webs can be calculated by using the provisions of the present design specification of the steel structures.
