| 摘 要： | 根据普通混凝土梁斜截面抗剪性能试验方法设计,对7根再生混凝土简支梁斜进行截面抗剪性能试验,研究再生混凝土梁斜截面受力特点和抗剪破坏机理,分析再生骨料取代率对再生混凝土梁斜截面抗剪性能的影响,最后探讨再生混凝土梁抗剪强度计算公式,认为GB 50010—2002《混凝土结构设计规范》中普通混凝土梁抗剪承载力公式对再生混凝土梁同样适用,具有一定安全储备,并基于工程要求建议更适用于再生混凝土梁的抗剪公式。

| Abstract: | According to the shear performance test of ordinary concrete beam,this paper designed and condusted the shear performance test of 7 recycled concrete beams which were simply supported,it was studied the forced characteristics and shear failure mechanism of recycled concrete beams,and analysis the influence of recycled aggregate replacement to the shear properties.Finally,it was discussed the shear strength calculation formula of recycled concrete beam,and considered that the shear strength formula of ordinary concrete beam in the Code for Design of Concrete Structures(GB 50010—2002) can still be used for recycled concrete beam,it contains a certain security reserve,and based on engineering requirement,is was suggested that a more applicable shear formula should be used for recycled concrete beam. |
