| 摘 要： | 通过对5根相同断面,相同配筋率,翼缘采用再生粗骨料取代率依次为0%、30%、50%、70%及100%的再生混凝土,腹板采用普通混凝土制备的T形截面叠合梁的弯曲试验,研究了各梁的受弯性能、变形特征及极限破坏形态等。结果表明:再生混凝土T形截面叠合梁的受弯性能和极限破坏形态与普通混凝土T形截面叠合梁类似;梁正截面的平截面假定依然适用;现行GB 50010—2010《混凝土结构设计规范》依然适用于再生混凝土T形截面叠合梁极限承载力的计算。

| Abstract: | The flexural behaviors of four recycled concrete T-shaped cross-section superposed beams and one natural aggregate concrete T-shaped cross-section superposed beam were contrasted by full-scale test. The experimental results showed the features of the flexural mechanism of these recycled aggregate concrete superposed beams were similar to those of the natural aggregate concrete superposed beams; the plane section assumption of normal section was still applicable for the recycled concrete superposed beams. The current"Code for Design of Concrete Structures"( GB 50010—2010) was still suitable for calculating the ultimate bearing capacity of the recycled aggregate concrete T-shaped cross-section superposed beams. |
