Abstract: Based on afive-story reinforced concrete frame structure reinforcement for the practical engineering background, the control structure with excessive displacement of the different reinforcement construction method, construction method and the effect of displacement control, ease of construction and engineermg costs were discussed. By ETABS analysis and calculation of the structure, the effectiveness of different methods of reinforcement and construction operation were compared, and a preliminary economic was studied.
Keywords: steel support structure; viscous dampers; displacement control
