Aseismic strengthening structure and aseismic strengthening method for reinforced concrete frame
The invention discloses an aseismic strengthening structure and an aseismic strengthening method for a reinforced concrete frame. A reinforced concrete column is additionally and closely arranged outside each outer column of the reinforced concrete frame, and a pile foundation is arranged below each reinforced concrete column. The side wall of each reinforced concrete column and the side wall of the corresponding outer column of the reinforced concrete frame are connected through a plurality of metal dampers in uniform intervals from the top, and the bottom of each reinforced concrete column is connected with a bearing platform through a rocking device and four pre-stressed steel bars close to a pin key. By the aseismic strengthening method, the problem that the reinforced concrete frame fails to realize a 'strong column and weak beam' failure mechanism in earthquake is solved; the metal dampers dissipate earthquake energy, cut down earthquake response and is replaceable after the earthquake; by the post-tensioned pre-stressed steel bars, the aseismic strengthening structure is enabled to restore, and quickness in post-seismic recovery of the structure is realized; since the aseismic strengthening method is completely carried out outside buildings, a series of problems caused by indoor construction can be avoided.
