高层建筑分散筒结构体系概念及其性能研究

The concept of high-rise building dispersion cylinder structure system concept and its performances study

首先阐述了分散筒结构体系的基本概念,然后通过对某高层建筑采用分散筒和框架—核心筒结构两种不同的结构方案进行抗风、抗震性能分析,分析结果表明:在大致相同混凝土用量和使用面积下,分散筒体系比框筒周期短;在水平荷载作用下,分散筒体系比框筒位移小。

The basic concept of dispersion cylinder structure system was illustrated firstly, then the wind resistance and seismic perforrnances of two different structural planning adopted in a high-rise building, i.e. dispersion cylinder and frame core tube structure were analyzed. The analytic results indicated that dispersion cylinder system period was shorter than frame structure system under the situation of approximate same concrete usage and utilization area, while dispersion cylinder system shift was smaller than frame structure system when horizontal loeding.
