Analytical Study on Steel Plate Reinforcement Effect at Beam-Column Joints in Reinforced Concrete Frame

This paper analyzed the reinforcement effect of concrete beam-to-column joints bonded with steel plate in reinforced concrete structures using finite element program. The limit load, ductility, and cracks of unreinforced model and reinforced model by steel plates were evaluated based on the analytical variations of reinforced steel plate area and thickness. As a result of analytical study, the maximum load of reinforced model by steel plate has 63% to 97.5% against unreinforced model. Also, to increase steel plate thickness has better performance than when steel plate area increases.
