- Abstract
- Buckling Restrained Braces(BRBs) show good seismic behavior. They do not dissipate energy, however, when they are subjected to wind. Hybrid Buckling Restrained Braces(H-BRBs), which can improve the wind performance of the BRB system,are a kind of hybrid damper system composed of a viscoelastic damper and BRBs. In this paper, the H-BRBs subjected to wind load was explored in the method of time history analysis for 3-dimensional model. The wind load for serviceability design was obtained from the wind tunnel test. Along wind and across wind load datas were used. Steel brace, buckling restrained brace, and H-BRB were compared in terms of the roof displacement, the roof acceleration, hysteresis loops. It was concluded that H-BRBs show good performance for the wind load and have improved the high-rise building performance at a serviceability level.
