Xie Gangkui Zhang Qilin' (1.Shanghai Aircraft Manufacturing Co. Ltd.Shanghai 200436 China: 2.China Construction Eighth Engineering Division Co.Lid Shanghai 200120 China; 3.School of Ciwil Engineering Tongji University Shanghai 200092 China) Abstract:The flexible overall lifting technique is put forward for the construction of the 30 000m2 COMAC roof which is made of solder ball space truss structure.The numerical simulation is carried out and the effect of unequal lifting on structural behavior is analyzed.The monitoring system is designed and installed for the forces and deflections of the structure during construction.Numerical analysis and engineering practicing show that the flexible overall lifting technique is with sufficient safety and obvious advantage in economy.
