摘要: ?？谟炅种挠^光塔采用鋼結構筒中筒結構體系,結構外筒為空間異形自由曲面,采用與空間結構類似的單層菱形網殼結構,內筒采用框架結構;三個塔樓之間通過空間曲線鋼連橋相互連接. 結構采用高層結構和空間結構的相結合的方法,形式新穎,建筑效果優(yōu)越. 結構具有構件間斷、承載力突變、局部不規(guī)則等超限項,是一種特殊形式的超限高層建筑. 介紹了該觀光塔特色結構體系及結構布置,并對結構強度、穩(wěn)定、舒適度等指標進行分析. 結果顯示:外筒殼構件計算長度系數與單層網殼結構存在一定的差別;采用加大基礎剛度和設置抗拔樁的方法可解決結構抗傾覆的難題;空間變標高的曲線連橋對主體結構影響較小,屬于弱連接的連體形式;鋼連橋的橫向和豎向振動舒適度滿足規(guī)范要求.

Abstract: The high-rise sightseeing tower for Haikou Center of Rainforest adopts the steel tube-in-tube structure system.The outer tube of the structure is a spatial special-shaped free-form surface which adopts a single-layer diamond reticulatedshell structure, it is similar to the spatial structure, and the inner tube adopts a frame structure. The three towers areconnected to each other through the spatial curved steel bridges. The structural form is novelly which combines the designmethods of high-rise structure and spatial structure to achieve excellent architectural effect. The whole structure is a specialtransfinite high-rise building with three transfinite terms which include component discontinuity, bearing capacity mutationand local irregularity. The characteristic of structural system and structural layout of the sightseeing tower were introduced,and the structural indicators such as strength, stability, comfort were analyzed. The result shows that there is a certaindifference between the effective length coefficient of the outer shell and the single-layer reticulated shell structure. Theproblem of structural anti-overturning can be solved by increasing the foundation stiffness and setting up anti-pulling piles.The curved bridge with spatial variable elevation has limited influence on the main structure, which belongs to the form ofweak connection. The lateral and vertical vibration of the steel bridge satisfies the requirements of the specification.
Keywords: Haikou Center of Rainforest; steel latticed structure; conjoined structure; anti-overturning analysis;vibration comfort
