Wide width beams are frequently designed in R/C moment resisting frame. Using mechanical anchorage for such beam reinforcements, development strength of a part which is not able to anchor in column section may be deteriorated. In order to solve this problem, the authors proposed new reinforcement detailing. In this study, R/C L-shaped joint connected with wide width beam using mechanical anchorage is tested. Consequently, the authors clarify ultimate strength and beam end ductility of these L-shaped joints.
