项目摘要

In recent years, it is reported in Japan that stirrups, as well as longitudinal steels, in T-shaped beams of bridge piers were ruptured at their bent corners mainly due to large ASR expansion. Therefore, it is essential to make clear the shear resistant mechanism of the beams, in which the stirrups are ruptured at the bent corner, in order to evaluate their residual shear capacity.In this study, the effects of expansion of concrete as well as bond and anchorage characteristics of stirrups on shear behaviour are investigated. Bond strength of ASR damaged concrete is also examined in order to evaluate the bond and anchorage characteristics of ruptured steels.From the test results, it is found that rupture of stirrups has relatively large influence on shear capacity of reinforced concrete beams. However, the degree of the influence depends largely on the anchorage characteristics of ruptured stirrups in ASR damaged concrete.
近年来,据报道,在日本,箍筋,以及纵向钢,在T形梁的桥墩,在其弯曲的角落,主要是由于大的ASR膨胀。因此,有必要弄清箍筋在弯角处断裂的梁的抗剪机理,以评估其剩余受剪承载力。试验结果表明,箍筋断裂对钢筋混凝土梁的抗剪承载力有较大的影响。然而,影响的程度在很大程度上取决于断裂箍筋的锚固特性在ASR受损混凝土。
