Abstract: The concourse of Shijiazhuang International Convention and Exhibition Center is a large and complex structural system, which is about 800m long and 100m wide. The roof supporting system consists of two structural forms of tree and Y shape column, and folded plate space truss is used for roof. The choice of structure styles was introduced, the loads value and analytical results were given, and indepth analysis on some key issues in structure design was carried out. Based on the elastic-plastic analysis, the seismic performance of the structure was fully studied, and the effective length factor of the columns and the node design were introduced.

Keywords: folded plate space truss; tree column; effective length factor; elastic-plastic analysis; seismic performance
