PURPOSE: A seismic retrofit method of Steel Reinforced Concrete(SRC) with an enlarged section using connection joint with anchor plate and steel bar tie is provided to effectively resist an earthquake for buildings by improving the load bearing capacity of the existing reinforced structures. CONSTITUTION: A seismic retrofit method of SRC with an enlarged section using connection joint with anchor plate and steel bar comprises a joint reinforcement plate(100), a plurality of fixing hardware, a steel skeleton member(500), a plurality of connecting hardware(220), and a steel wedge(600). The joint reinforcement plate is installed on the front surface of an existing concrete structure(50) and is equipped with a plurality of anchor through holes in the longitudinal direction. The fixing hardware forms a ∩-shaped loop by installing along the surface of the joint reinforcement plate. The steel skeleton member is installed along the surface of the existing concrete structure at regular intervals. The connecting hardware forms a U-shaped loop by combining along one side of the steel member. The steel wedge passes the intersection of fixing and connecting hardware and parallel positioned to the steel frame in the longitudinal direction. |
