Abstract
Ultra High Performance Concrete (UHPC) is a superior structural material with high strength and durability. The main objective of this study is to investigate behavior of the lap-spliced reinforced joints in UHPC. The lap-spliced joint type has simple details but it is expected to be highly effective method of joints in UHPC structure because of the high bond stress of UHPC. The static test was performed to verify the effect of the joint in the UHPC bridge deck slab. The major parameter considered in experimental plan was lap-spliced length and the strength of UHPC. Test results show that the minimum lap-spliced length which behaved similar to the continued reinforcement test specimen in strength and ductility was 150 mm (5.91 in.).
