[摘要]對11個(gè)具有不同截面尺寸、粘結(jié)長度、混凝土強(qiáng)度等級、保護(hù)層厚度、配箍率的型鋼混凝土短柱進(jìn)行了試驗(yàn)研究。測量的關(guān)鍵參數(shù)是型鋼混凝土之間的粘結(jié)應(yīng)力和滑移。型鋼的粘結(jié)長度、混凝土強(qiáng)度等級、混凝土保護(hù)層厚度、配箍率是影響粘結(jié)性能和粘結(jié)強(qiáng)度的主要因素。提出了型鋼翼緣和腹板處的粘結(jié)應(yīng)力分布模式及極限粘結(jié)強(qiáng)度的計(jì)算公式。

Abstract:To study the bond-slip performance between structural steel and concrete, the test concerned eleven short columns with the different configuration, such as cross section dimensions, bond length, concrete strength, thickness of concrete cover and the rate of stirrup lateral, was carried out. Key parameters measured are bond stress and slip between structural steel and concrete. The bond length, concrete strength, thickness of concrete cover and rate of stirrup lateral are the main factors affecting the bond behavior and the bond capacity. The distribution mode of bond stress is noted on the flange and the web of structural steel. Moreover, a formula calculating ultimate bond strength between structural steel and concrete is proposed .
Keywords:steel reinforced concrete; bond mechanism; bond stress; bond strength
