Abstract:The structural overview and design principle of reconstruction of Xiamen International Conference Center were introduced. The design scheme of the newly-added 25-2m-span steel structure floor was introduced, and the scheme adopted the method of removal of part of the original structure and reduction of the original floor surface layer, and reasonable arrangement of structure and control of new structural loads could ensure the original pile foundation meet the reconstruction requirements. Special study on floor vibration design was conducted, and additional damping system could meet pedestrian comfort requirements. Several connections were designed for newly-added beams and original columns, including hinges and sliding connections, which could provide reference for similar reinforcement and reconstruction project.

Keywords:Xiamen International Conference Center; reinforcement and reconstruction design; beam column joint; comfort
