RELATED ISSUES OF ACCUMULATION HOISTING TECHNOLOGY OF LONG-SPAN LATTICE FRAMED STRUCTURE AT BEIJING INTERNATIONAL AIRPORT

For the problems of different layers,different heights and the existence of dislocation,the accumulation-hoisting construction technology of unit assembly-unit lifting-integral assembly-integral lifting is proposed for Xinhua airlines hangar in Beijing International Aairport.The related issues of this construction technology is analyzed and studied,such as the closure construction method,numerical simulation and structural analysis based on integral model.This construction technology is proved to be effective through the accumulation-hoisting construction of long-span lattice framed structure for Xinhua airlines hangar,and the research results can be used as the reference for the construction process of this kind of structures.
