| Abstract: | In order to investigate the bond slip relationship of reinforcing bars under compressive condition,a series of push out tests of the specimens with short anchorage length were done using the Laser Displacement Sensor with high precision.The precise bond slip values and whole bond slip curves were gained from the tests.According to the test results,the failure process for the compressive bond slip of the bar in concrete was described in details,which can be divided into five stages: elastic stage,slip stage ... |
