Abstract
An effective method for the reinforcement of vertical construction joints in a reinforced concrete beam with steel plate was experimentally studied. The construction joints presented at the mid-shear span of a RC beam It was found that the flexural and shear strength of RC beams with construction joints that were reinforced with steel plates were similar to those for a RC beam without construction joints. In addition, the RC beams failed in bending with the tension reinforcement yielded, which was also similar to the failure mode for RC beam without construction joints. Furthermore, the thickness and width of the steel plate had effects on the behavior of RC beams reinforced with the steel plates.
