EXPERIMENTAL STUDY ON THE SHEAR MECHANICAL BEHAVIOR OF STEEL REINFORCED RECYCLED COARSE AGGREGATE CONCRETE BEAMS
In order to reveal the mechanism behavior of oblique section of steel reinforced recycled coarse aggregate concrete beams,9 specimens were designed for static test,the experiment considered the impact of recycled coarse aggregate replacement ratios,ratio of shear to span two variable parameters.Through this test,the whole mechanical process and failure patterns of the specimens were observed,obtained the ultimate bearing capacity and load-displacement curves parameters,and analyses the impact of aggregate replacement,ratio of shear to span and concrete strength on the failure behavior and mechanical behavior of the specimens.The results show that:according to different ratios of shear to span,there are shear compression failure and shear bonding failure two types of shear failure were obviously seen,and the beams have good bearing capacity and deformation performance.
