Abstract
In principle, lap splices of large-diameter deformed bars in reinforced concrete are not acceptable. Accordingly, the main methods used in joining these bars are welded splices and many kind of mechanical connections. However, these methods are accompanied by problems about quality contorol, need for special skills, etc. To solve these problems, a lap splices with splint-bar reinforcement was developed. In this report, results of flexural and shear-flexural strucutal experiments on reinforced concrete members containing the joint method developed are explained. It was shown that beams or columns with short lap length possess sufficient strength and ductility for practical use.
