This paper deals with the shear bond strength of steel encased reinforced concrete (SRC) members. A theoretical strength is led based on the upper bound theorem in plastic analysis, assuming idealized deformation and failure surface in members. The proposed formula indicates that the shear bond strength depends on an axial load level, and its adequacy is confirmed empirically. Bond characteristics between encased steel and concrete are also examined empirically, and it is concluded that the influence of the bond cannot be neglected when cross-H shaped steel is encased in the members. Finally, the condition that such a brittle failure can be avoided is reconsidered.
