| Abstract: | The roof of Chaoshan Airport takes the shape of irregular steel space truss and it was lifted as a whole during construction.Geometrical model was built for this structure and boundary conditions were applied in finite element analysis program.Analyses were performed for synchronized hoisting and unsynchronized hoisting.The forces of the lifting frame and the stress state of the welded ball joint were then analyzed to provide theoretical support for the safety of the construction. |
