Test on Bending Performance of Recycled Concrete Composite Beams
摘要
Abstract
Three recycled concrete composite beams with tensile reinforcement ratios of 0. 5%, 1. 0%, 1. 5% are respectively designed. The prefabricated part uses conventional concrete while the cast-in-place part uses recycled concrete. In order to compare with the conventional concrete beam, a conventional concrete beam is also designed in which the replacement ratio of the recycled coarse aggregate is 100%. The midpoint deflections, ultimate loads, the distribution of the cracks, and failure characteristics have been obtained during the bending test. The non-linear finite element analysis is carried out by the software of Ansys. The experiment results and numerical analysis show that the recycled concrete composite beams behave similarly as the conventional concrete beams, the theory and design method applied to the conventional concrete beams can also be suitable to the recycled concrete composite beams. The deflection calculated according to the GB 50010-002 can still be applied to the recycled concrete composite beams after mordified by a factor 0. 8.关键词
