Design and analysis for wind-induced vibration control of roof truss of high-rise structure

This paper presents the design for wind-induced vibration control of roof truss, with the calculation results and experiment performance of energy dissipation damper given. The results of analysis show that the performance of energy dissipation damper will increase with the increase of the thickness of damping material and steel plate. The dynamic response of roof truss and main structure will be reduced effectively when the damping device is disposed, and the relative floor displacement of roof truss will be meliorated greatly, with the biggest control effect of floor displacement angle by 41.4%, the biggest control effect of the top displacement of truss by 13.9%, and the biggest control effect of the acceleration of main structure by 38.3%. Using the energy dissipation technique in this project demonstrates obvious technical and economic benefit.
