【Abstract】 Aiming at the large-span and heavy-duty structure in actual engineering, a new type of prestressed composite steel truss structure is proposed. The static analysis of the new prestressed composite steel truss structure is carried out by using the finite element analysis software ANSYS to study the various components of the structural system. The force and deformation performance of the stage and tension stage indicate the rationality and reliability of the new prestressed composite steel truss structure design.更多还原
