Anti-symmetric loading tests of reinforced concrete beams confined with FRP sheets were carried out to verify the bond strength equation that was proposed in the preceding paper. The FRP sheets used were carbon and aramid types, and the main test variable was the amount of FRP sheets (P_<wf>=0,0.08,0.16,0.24,0.32%). The observed shear forces at bond splitting failure of the beam specimens were compared with the calculated ones which were drawn from the combination of the bond strength equation and "truss and arch theory". The bond behavior of the member with 2-layered longitudinal bars was also discussed. Based on the beam tests, it was shown that the proposed equation could evaluate the contribution of the FRP sheet on the bond strength of RC members.
