Abstract

Abstract

In order to reveal the flexural behavior of steel reinforced recycled coarse aggregate concrete beams，6specimens were designed for flexural test． The study considered two impact parameters，which are coarse aggregatereplacement rate and concrete strength grade． Through this test，the whole mechanical process，crack distribution andfailure behavior of this kind of specimens were observed，and obtained the stress-strain distribution curves，theultimate bearing capacity and load-displacement curves parameters． Based on the test data，the impact of coarseaggregate replacement rate and concrete strength grade on the mechanical behavior of steel reinforced recycled coarseaggregate concrete beams was deeply analyzed． The result shows that the replacement rate influences the bearingcapacity of steel reinforced recycled concrete beams，and with replacement rate increases，the bearing capacityincreases from 5. 95% to 17. 63%; during loading process the section strain agreed with the plane sectionassumption，and the beams have good bearing capacity and deformation performance． Finally，put forward normalsection strength calculation method of steel reinforced recycled coarse aggregate concrete beams． The researchconclusions can be a help to relevant study and engineering application．
