钢筋再生混凝土梁的受弯性能

Flexural behavior of reinforced recycled aggregate concrete beams

基于国内外大量相关研究成果,对钢筋再生混凝土梁的受弯性能进行了较为全面系统的分析,主要包括平截面假定对再生混凝土梁的适用性、钢筋再生混凝土梁的破坏形态、极限承载力、变形、刚度以及裂缝等。研究结果表明,与钢筋普通混凝土梁相比,钢筋再生混凝土的破坏形态、极限承载力基本相同,但是钢筋再生混凝土梁的变形较大,刚度低。同时发现平截面假定也适用于受弯的钢筋再生混凝土梁。

Based on a large number of the related t results from published literature, a review of the flexural behaviour of reinforced recycled aggregate concrete beams was presented,including the applicability of the plane section assumption for reinforced recycled aggregate concrete beams,the failure mode,the flexural bearing capacity,and the deformation as well as the stiffness of reinforced recycled aggregate concrete beams.It was found that the plane section assumption is applicable for reinforced recycled aggregate concrete beams.Compared with normal concrete beams, the failure mode and the flexural beating capacity of reinforced recycled aggregate concrete beams are similar, however, the deformation is somewhat larger and the stiffiness is smaller.
