Research and Design of Heifei Swimming Gymnasium Based on Seismic Performance
of Structure Deformation/Zhang Sheng, Gan Ming, Ji Qing, Guo Chengxi（Beijing Institute of Architectural Design Beijing 100045,China）
Abstract:Heifei swimming gymnasium is composed of space frame structure with a symmetric  support system. The seismic displacement of the project can not meet the requirement of the seismic code so that the seismic performancebased design is introduced to obtain the internal force and deformation in rare earthquake. The elastic and plastic analysis result shows that the project has not permanent drift. The structure substantially retains original strength and stiffness that shows the post earthquake damage state of this project is very light.
Keywords:seismic performance design; elastic and plastic analysis; spatial structure
