Abstract
In general, the bond performance of reinforcement is assessed using pullout specimens. However, when ribbed bars are considered, several objections regarding the form of such tests become apparent. In view of this, a study was conducted to establish whether pullout tests in general, and the BS4449 bond test in particular, provide a valid measure of bond performance of deformed bars. It was shown that there are no strong reasons to abandon pullout methods of test, despite their being unrepresentative of practical conditions. A suitable correlation between performance in the BS4449 bond test and BS8110 design ultimate bond strengths was proposed, and the need to develop a similar correlation in respect of crack and deflection control performance was identified.
