Research And Application Of Seismic Reinforcement Of A Reinforced Concrete Frame Structure

At first,this paper summarizes the present situation of seismic reinforcement technique,and briefly describes its reinforcement technique theory and scope of application,introduced the energy dissipation damping viscous dampers in the reinforcement technology of reinforcement principle and computing theory;Then,the concrete office building is combined with the concrete construction of the concrete office building.Reinforcement process using PKPM and SAP2000 software modeling analysis in the first place,by the results of the analysis combined with engineering characteristics determine appropriate reinforcement scheme,the structure of using additional viscous dampers in the earthquake dynamic time history analysis of performance of the structure before and after reinforcement.Results show that the viscous dampers after reinforcement of buildings can better resist seismic action,on the interlayer shear force and displacement between layers has great weakened,make structure seismic performance indicators meet the specification requirements,to achieve the effect of reinforcement.
