摘要
广州塔外筒斜柱和斜撑在一椭圆直纹面上,轴线相交,而环杆通过与斜柱相贯伸出的牛腿连接形成倾斜的椭圆环,环杆通过牛腿对外筒施加约束。外筒节点必须设计成刚性节点,才能满足整体稳定和局部稳定。主要介绍了刚性节点及刚性节点的试验验证、节点的设计构造及有限元分析。
The frame tube structure of Guangzhou Tower is composed of inclined column, bracing and inclined elliptical ring. The axes of the inclined column and the bracing are intersected. The elliptical ring connects the oblique column with the bracket stretched out the column, and imposes constraints to the inclined column. In order to meet the overall stability and local stability requirements, the joints of the frame tube must implement rigid connection. The experimental verification of the rigid joints, the construction of joints and finite element analysis results were described.
