In this article, authors introduce a construction method of steel wire cable upper pulling shaped steel suspension scaffolding that engineers adopt double steel wire cables and control tension degree of every wire strand cable to finally removal turn bolts.

The design and construction of super-large span cantilever steel truss,120m above ground,as temporary operating and supporting flat,are introduced.

Based on these, the theory studies and design of the wind vibration control for a large cantilevered steel spatial truss with circular tube viscoelastic dampers of the roof engineering at Hefei Olympic Center is finished and this building engineering has been set up and got a good social benefit and economic benefit.
