Abstract: The whole lift design and analysis of steel roof in A380 air craft hangar are presented. Some key mechanicalproblems are outlined and analyzed. To solve these problems, a hoisting process analysis procedure based on an integratedmodel is proposed. In this model, the interaction of a lifting steel roof, the latticed towers and the cables are consideredautomatically, as well as the influences of wind loads and temperature change are involved in the analysis. The continuouschecking of the deformation and stress distribution during hoisting process in A380air craft hangar are monitored and traced,and some important references are given as the guidelines of the lifting construction.
