In this research, the experimental works were conducted to study the lap strength of the headed reinforcements with confinement provided by stirrups or tie-down bars. Eleven lap splice specimens were tested. The variables in this study were: confinement details and lap length. The initial crack of the specimens lapped developed at the heads of reinforcements. Bearing stress and confinement details contributed to increase strength and deformation.
