( Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: Beijing Shijitianqiao building needs seismic reinforcement and reconstitution for the change of its building function. Based on the analysis and checking calculation of the original structure,frame+ damper structure and frame-shearwall structure were analyzed. The design and calculation method of damper was introduced. Through the results of analysis, the advantages and disadvantages of the two types were compared. Finally the connection method of joints was introduced. This project can provid a reference for the retrofit design of sinular structures.
Keywords: seismic appraisal; retrofit; energy dissipation; joints connection
