ABSTRACT
ABSTRACT: As the size of structures become larger in the current construction trends, connection of reinforcing rebar for concrete structures will come an important issue for RC structures. Most common rebar connection methods available are the lap splice joint, pressure welded joint, and the mechanical joint methods. When thick rebar’s are required to be connected, however, design codes recommends the lap splice joint to be avoided. This is because of potential difficulties in placing concrete in complex rebar area and securing sufficient cover depth, and uncertainty of bond between rebar and concrete. This study will present the results of independent study of mechanical reinforcement splices conducted at the Anadolu University of splicing systems marketed in Turkey. The results of this testing program have shown that mechanical splices are indeed capable of effectively connecting reinforcing bars together and that many are capable of producing bar breakage as the failure mode.
