Abstract:
Changchun Auto Exposition Hall engineering adopts an unique aerial wide-span wheel hub shape. The front facade of the structure is a eccentric ring. The radius of the inner ring is 21.65m and the outer ring is 39.85. The structure top is about 63.55m high. Considering that the steel structure has arch components and has multidirectional bearing base, reasonable hoisting sequence, method and lateral stability measures are adopted to ensure the stable and safe state of structural components after being positioned during hoisting, and the construction sequence of “gravity center calculation of space component, hoisting simulation, hoisting positioning”is used. Favorable effects are realized.
