TENSILE BOND STRENGTHS OF DEFORMED BARS OF HIGH-STRENGTH CONCRETE

Results are presented from an experimental study into the tensile bond strengths of deformed bars embedded in high-strength concrete. Twenty beam specimens in two series were tested statically to measure both the splice strength and the development strength. Other variables included concrete strength, anchorage length, and amount of transverse reinforcement. The bond performance of high-strength concrete without silica fume was similar to that of normal-strength concrete. The equivalence between the tensile development length and the tensile splice length for high-strength concrete was established. The applicability of existing models to estimate bond strength of high-strength concrete was studied. The tests revealed that total confinement beyond the currently accepted limit was still effective for the bond action of high-strength concrete.
