Abstract:The design of structure truss in 4^# loading dock area of Suzhou Expo Center is introduced. By making use of the mezzanine height of central mechanical/electrical plan and setting reasonably the member shape of steel truss, steel truss in supporting axial force and large stiffness in truss plan are taken advantage, which may be a reference for the design of the structures having large span and supporting heavy load.

Keywords:loading dock; exhibition hall; steel truss; axial force; stiffness
