description abstract | The bond performance of reinforcing bars to concrete, an indispensable factor in designing reinforced concrete structures, is deeply influenced by the stress states of surrounding concrete. In recent decades, although self-compacting lightweight aggregate concrete (SCLC) has gained popularity in architectural engineering, the bond stress-slip relationship of deformed bars in SCLC under lateral tension remains unknown. In this study, 179 pullout tests were performed to examine the local bond stress-slip behavior of deformed bars in SCLC. In addition, the effects of various parameters on the ultimate bond strength and the slip at the ultimate bond stress, as well as the residual bond strength, were analyzed quantitatively. The results showed that both the bond strength and slip at the ultimate stress decrease with the increase of lateral tension regardless of whether it is in pull-out or splitting failure mode. In addition, an empirical formula was proposed that gives a reasonable prediction of the measured bond stress-slip curve of the SCLC. | |
