摘要
本文依据3个小剪跨比高强混凝土牛腿构件在竖向荷载作用下的受剪破坏试验结果,对不同剪跨比条件下牛腿构件的破坏过程和破坏形态进行了对比分析,总结了剪跨比对牛腿构件承载能力的影响规律。结果表明,小剪跨比牛腿的破坏形态可具体分为斜剪破坏和斜压破坏两种,剪跨比增大会导致牛腿的承载能力减小。
Based on the shear failure test results of three high-strength concrete corbel members with small shear span ratio under vertical load, the failure process and failure mode of the corbel members with different shear-span ratio were compared and analyzed, and the influence law of shear-span ratio on the bearing capacity of the corbel members was summarized in this paper. The results show that the failure modes of the corbel with small shear-span ratio can be divided into two kinds, namely diagonal shear failure and diagonal compression failure, the increase of shear-span ratio will lead to the decrease of the bearing capacity of the corbel.
