摘要：为了解调谐质量型防屈曲支撑（TB）风振控制效果,以某拟建高层办公楼为案例工程,对其做TB调谐质量阻尼器设计.基于有限元模型的附加阻尼法和风速度时程法分析结果表明：TB结构较BRB结构,顶点最大位移和最大层间位移小12%~15%,最大加速度小20%.统计显示,TB结构脉动反应比BRB结构小19.77%,位移均方差小16.05%,加速度均方差小22.09%.基于投资-收益的性能对比分析显示、在相近投资条件下,TB结构具有明显的性价比优势.
In order to understand the control effects on wind-induced vibration of tuning mass damped buckling-restrained brace( TB),TB tuned mass damper design( TB / TMD) was conducted based on a high-rise office building to have been built as a case project. Analysis results obtained by the additionaldamping method and wind speed time-stepping method in finite element model show that the maximum apex displacement,maximum inter-story displacement and maximum acceleration of TB structure are12% ~ 15% and 20% less than those of BRB structure,respectively. According to statistics,the TB structure 's pulsing reaction, mean square deviation of displacement and mean square deviation of acceleration are 19. 77%,16. 05% and 22. 09% less than those of BRB structure, respectively.Comparative analysis of investment-profit performance shows that the TB structure presents obvious advantages of cost effectiveness under similar investment conditions.
