[提要]  報(bào)告了12個(gè)試件的抗剪極限承載力試驗(yàn)。試驗(yàn)結(jié)果表明，在單調(diào)靜力荷載條件下，單面連接角焊縫有良好的承載和變形性能，對(duì)H形截面鋼構(gòu)件腹板剪切失穩(wěn)后的極限承載力的不利影響很小，可以按照鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范有關(guān)規(guī)定計(jì)算腹板抗剪極限承載力。

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.
Keywords: one-side fillet weld; thin-welo member;  buckling; post-buckling; capacity; ultimate resistance shear; experimental research; light-weight steel elements
