摘要
本文通过集中荷载作用下的１８根超高强混凝土有腹筋约束梁的抗剪试验研究，分析了超高强混凝土有腹筋约束梁的破坏形态和抗剪性能，着重研究了混凝土强度、配箍特征值及剪跨比对试件抗剪强度的影响。
In this paper, the failure patterns and the shear strength of super-strength concrete beam constrained with web bars and under concentrated loads were analyzed. The effects of concrete strength, stirrup ratio(the stirrup characteristic value) and shear span ratio on shear strength were thoroughly researched through the tests of eighteen super-strength concrete beams constrained with web bars and subjected to concentrated loads.
