dc.description.abstract To assess the viability of the external confinement of normal-strength concrete beam-column joints with carbon fiber-reinforced polymer (CFRP) sheets in increasing the bond strength of hooked bars anchored in the joints, 12 hooked bar specimens were tested. The variables were beam tensile bar size, anchorage length, mode of confinement of the beam hooked bars in the beam-column joint (whether the hooked bars were anchored within or outside the column reinforcement cage, denoted as confined specimens or unconfined specimens), and presence or absence of FRP wraps. The specimen simulated the rigid connection of a cantilever beam to a column. The tensile beam reinforcement consisted of two bars anchored in the base column using hooked-bar anchorages. Test results indicated that FRP sheets were effective in increasing the anchorage capacity and the ductility of the load-deflection history for both unconfined and confined specimens. However, FRP sheets had a more significant influence on unconfined specimens than companion confined specimens. As compared with unconfined specimens without FRP wrapping, unconfined FRP specimens had an average of a 23percent increase in bond strength, confined non-FRP specimens had an average 30percent increase in bond strength, and confined FRP specimens had an increase of 54percent. © 2009 ASCE.
