摘要
实际工程中,将水箱设计成调频质量阻尼器TMD以控制结构的风振加速度是一种经济可行的方法。在有关的风振控制理论基础上,基于现行荷载规范并结合PKPM编制了计算程序,可方便地确定TMD的最优设计参数及其对超高层建筑的控制效果。通过算例分析表明这种方法简便易行,具有应用价值。计算还表明,TMD主要控制楼层风振加速度,尤其是结构阻尼比较小时,还可改善使用的舒适性。
Using water tanks as the tuned mass damper(TMD) of a building to control the wind vibration is recognized as an applicable and economical method in practice.Based on studies related to the wind vibration control of a building and the current load conventions in the code,a new computational program,combined with the computer program PKPM,was written to conveniently choose the optimum design parameters of a TMD for a super high-rise building and also to analyze the effects after the TMD is applied. Sample calculations have shown that this program is workable and convenient in use,and is applicable in real life designing.Calculations have also indicate that the TMD mainly controls the acceleration of a building's wind vibration.Especially for buildings with less structural damping effect,proper TMD can improve the serviceability of those buildings.
