摘要
介绍了由三栋250m高的超高层建筑通过在顶部设置连桥连接形成的复杂三连体结构。三栋塔楼结构体系为钢筋混凝土的框架—核心筒体系,顶部连桥采用钢结构,连体部分呈斜交错位且不闭合的形式,整体动力特性复杂。文中介绍了此连体结构的基本结构概念,并对其在罕遇地震下的结构性能进行了验算。结果表明整体结构方案合理有效,在罕遇地震作用下的损坏均处于可控范围内。
A complex triplex structure formed by three 250m high super high-rise buildings connected by bridges at the top was introduced.The structural system of the three towers is a reinforced concrete frame-core tube system,and the top bridge adopts a steel structure.The interconnected parts are arranged in a diagonal and overlapping manner,without forming a closed loop,resulting in a complex dynamic behavior.The article presents the basic structural concept of this interconnected structure and verifies its structural performance under rare earthquakes.The results show that the overall structural design is reasonable and effective,and the damage under rare earthquake events is within a controllable range.
