Analysis on the Influence of Not Synchronization for Hoisting Extra Large Solder Ball Grid Roof

Analyze the safety of flexible hoisting the overall roof with Sap200014.0 while constructing the COMAC ministry of installed plant. Find the influence of the overall structure stiffness under kinds of hoisting step and the bigger step which the structure can stand. The numerical simulation is carried out and the effect of unequal lifting on structural behaviors is analyzed. Numerical analysis and engineering practicing show that the overall flexible hoisting technique is with sufficient safety and obvious advantage in economy. This method can provide some experiences to the construction and fabrication of the steel member of the project.
