Abstract
The authors have proposed a method of joining the rebars of RC wall structures such as box culvert. It is effective for productive improvement of wall member with mechanical splices at the same section regardless of the plastic hinge zone. There are many reports where wall member's deformation capacity is raised by using mechanical splices at the same section. However, it's mechanism has not been completely explained yet. This report shows a buckling resistance test for main bars using Japanese class “A” mechanical splice in full scale sized wall specimen tested under cyclic seismic loading. As a result, mechanical splices at the plastic hinge zone of wall members effectively improved the buckling resistance of rebars, and the member's deformation capacity was superior than joint-less specimen.
