A SEISMIC RETROFIT SYSTEM FOR REINFORCED CONCRETE STRUCTURES

摘要

PURPOSE: An earthquake-proof reinforcement structure of a reinforced concrete building is provided to ensure earthquake-resistant performance of the reinforced concrete building and to facilitate construction and maintenance. CONSTITUTION: An earthquake-proof reinforcement structure of a reinforced concrete building comprises a first channel(10), a second channel(20), a hysteretic damper(30), a vertical stiffener(40), and a horizontal stiffener(50). The first channel is formed in a U shape and is horizontally attached to a reinforced concrete beam(1). The second channel is formed in a U shape and is vertically attached to a reinforced concrete column(2). The hysteretic damper is comprised of four dampers(31) which are installed between the first and second channels for reinforcing the first and second channels. The vertical and the horizontal stiffener are coupled to the interior of the first and the second channel to reinforce the first and the second channel, respectively.
