摘要
风荷载对超高层建筑结构的安全性和舒适性有着重要的影响,研究超高层结构风振控制方法具有较大的工程实用价值.本文选用一栋高304.2 m且带有伸臂加强层的超高层建筑作为算例,设置调谐质量阻尼器、伸臂加强层阻尼体系以及两者混合控制的方案进行三维有限元建模计算,对比不同控制方法的控制效果.结果显示:调谐质量阻尼器的控制效果较其他方案稍弱,设置伸臂加强层阻尼体系和混合控制方案都能显著降低结构的风振响应,混合控制方案仅从控制效果方面来看在所给的四种方案中最优.
Wind loads exert an important influence on the safety and comfort of super high-rise buildings.Naturally,studies of wind-induced vibration control methods for super high-rise structures will offer great engineering practical values.In this study,a 304.2 m high super high-rise building assembled strengthened story is selected as an example.We then set the tuned mass damper(TMD),damped outrigger system,and a hybrid control scheme for three-dimensional finite element modeling computations.Results show that the control effect of TMD is slightly weaker than that obtained by using other schemes.The damping system of the damped outrigger system and the hybrid control scheme can significantly reduce the wind vibration response of the structure.Finally,the hybrid control scheme yields better control effects.
