摘要
融科C座63m跨度玻璃大堂采用悬索、拉索和揽风索相结合的结构形式,其规模在同类结构中居世界第一。针对工程特点,重点介绍了方案设计的改进演变过程、结构细部设计中的优化及最终采用的构造方法,其中包括提出的两种新型的钢索锚固节点形式。为了确定该柔性结构的体型系数和风振系数,进行了刚性模型和弹性模型的风洞试验,对试验内容和成果进行了总结介绍。实践证明,这种由不同类型拉索组合的结构是一种高效、先进的大跨度结构形式。
The combination of three types of cables is adopted in the Curtain Hall in Raycom C Project, which is the largest span of this kind of structure in the world. It is introduced that the process of structural scheme design and detail design, including two new kinds of joint for anchoring cable. To determine the shape factor of wind load and dynamic wind effect factor of this flexible structure, wind tunnel tests with rigid model and elastic model were done, and the contents and results are summarized. This cable-combined structure is a kind of high efficient and advanced structure.
