黏滞阻尼器在超高层结构体系中的效率研究

250m以上的超高层结构主要有框架-核心筒、框筒-核心筒和巨型框架-核心筒等三种结构体系．由于超高层结构的高宽比通常较大（5以上），结构的侧向变形往往成为控制因素．随着消能减震技术的不断成熟，黏滞阻尼器越来越多的应用于建筑结构领域．本文分别将黏滞阻尼器均匀布置在上述三种超高层结构体系中，对比其消能减震效果并分析原因，最后建议了黏滞阻尼器在这些结构中的较优布置．

Study on Efficiency of Viscous Fluid Damper in Super High-Rise Structure Systems

Frame-core tube structure, tube-in -tube structure and mega frame-core tube structure are most commonly used in super high-rise buildings. For the large aspect ratio of super high-rise structures, usually larger than 5, the lateral deformation is the controlling factor in many cases. With the continuous development of energy dissipation technologies, viscous fluid dampers are increasingly brought to building structures. This paper uniformly arranged viscous dampers into the three structure systems mentioned above, compared their energy-dissipation efficiency and analyzed the reasons, finally suggested the optimal locations for viscous fluid dampers in these structures.
