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.
The structure of the super high-rise above 250m consists of three structural systems: frame-core tube, frame tube-core tube and mega-frame-core tube etc. As the aspect ratio of the super-tall structure is usually large (above 5) Deformation often becomes the control factor.With energy-saving damping technology continues to mature, more and more viscous dampers are used in the field of building structure.In this paper, the viscous dampers are uniformly arranged in the above three kinds of super high-rise structural system , Compared its energy dissipation effect and analysis of the reasons, and finally proposed a viscous damper in these structures in the optimal arrangement.
