Beam specimens of lapped splice bars with high-strength concrete were tested to determine the bond splitting strength at the critical section of a beam, under shear-bending stresses for 10 specimens and under pure bending stress for 3 specimens. Shear-bending load was applied to the longitudinal lapped splice bars of a beam of high-strength concrete until they fracture in side-split mode. The main variables tested are lapped splice length and transverse reinforcement ratio. The bond splitting strength of shear-bending test specimens is larger than that of pure bending test specimens. The existing equation of bond splitting strength, which takes into account of shear-bending stress, was proved to give satisfactory estimation of the bond splitting strength of lapped splices in the shear-bending test specimens.
