Dual vibration control design of a super high-rise steel structure residence
【摘要】 本论文旨在探讨超高层钢结构住宅在沿海地区面临的风振舒适度问题,并结合实际工程案例,介绍黏滞阻尼技术在地震和风振双激励下的振动控制方法。本文以一座地上44层、地下3层住宅工程为例,结合工程概况和风洞气动弹性试验结果,分析了黏滞阻尼减振系统在提高结构舒适性和实现风振/地震双控方面的效果。通过对超高层结构的设计和振动控制手段的研究,为类似工程提供了经验和参考。研究发现,黏滞阻尼减振系统不仅能改善风振下的舒适性,还能提高地震时的冗余度,实现了双重振动控制的性能目标,并具有较好的经济性。
【Abstract】 The purpose of this paper is to discuss the problem of wind-induced comfort of super high-rise steel structure residential buildings in coastal areas and introduce the vibration control of viscous damping technology under both earthquake and wind-induced excitation combined with practical engineering cases. Taking a 44-storey above ground and 3-storey below ground residential project as an example, combined with the general situation of the project and the results of wind tunnel test, the effect of viscous damping vibration reduction system in improving structural comfort and realizing wind-induced vibration/earthquake dual control is discussed in this paper. The design of super high-rise structure and the study of vibration control methods provide a reference for similar projects. It is found that the viscous damping system can not only improve the comfort under wind-induced vibration, but also increase the redundancy during earthquake, which achieves the performance goal of dual vibration control and has economy.
