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.

7m of an electric dispatch and communicating center mansion,illustrates the scheme design and construction technology of bearing strutting of cantilever structure,ensures the construction safety and construction quality in the engineering.

Farther,an actual building destroyed by typhoon was investigated employing the material and geometrical nonlin-earity method and the failure principium of cantilever space truss under typhoon was studied.
