An experimental study was conducted to propose an improved joint in the beam with non-uniform depths of cross-sections. The tested joint detail consisted of headed bars and 180-degree hooked bars. The parameters are the splice length and the confinement effect of strrups in lap zone. The increase of lap length and the confinement detail of strrup reinforcement in the lap zone did not affect the initial stiffness. It can be concluded that the proposed joint detail would be applicable to practical design by using the load transfer mechanism by the effects of confinement details.
