Abstract：
During the main tower building construction of Glory Xi'an Financial Center, cantilever truss support-free construction method was used after comparison among construction schemes. Detailed construction scheme was designed and cantilever truss support-free integral lifting method was developed, using chain block system to adjust the elevation and plane deviation. It was proved that support-free construction scheme is reasonable and feasible, satisfying the design and specification requirements for quality, safety, scheme and cost.
