Test and FEM Simulation on Shear Transfer Behavior of Recycled Aggregate Concrete

摘要：

　　In this study, the shear transfer behaviors of ordinary concrete and recycled aggregate concrete (RAC) are investigated by conducting tests on push-off specimens.The results indicate that the shear capacities of recycled concrete are similar to those of ordinary concrete.The shear stress-shear displacement curve shapes of ordinary concrete and recycled aggregate concrete are consistent.The shear capacities were analyzed by ABAQUS software.It has been shown that the ultimate shear stress of recycled concrete is almost the same as that of ordinary concrete.The simulated shear stress-shear displacement curves are close to the tested curves.The FEM results are well consistent with the test results.It can be concluded from the parameter study that, the shear transfer strength of RAC is improved with the increase of constrain rigidity as well as the recycled concrete strength.
