摘要
根据国家体育场大跨度钢结构柱脚的受力特点,提出一种适用于大型钢结构的新型半埋入柱脚形式。在柱脚-混凝土承台模型的有限元分析与柱脚锚固件的锚固性能试验的基础上,形成了大型柱脚-混凝土承台的设计方法。该类柱脚在国家体育场钢结构中的实际应用情况表明,本文提出的柱脚形式与设计方法对于大型钢结构具有很好的适用性和广泛的应用前景。
A new type of semi-embedded column base which is able to use in large-scale steel structures is presented according to the internal force features of the National Stadium. The corresponding design method is developed based on the FEM analysis for the column base ＆ RC-pile cap model and experimental study for anchorage performance of the anchorage element of the column base. The successful application of the design method for the column base ＆ RC-pile cap in the National Stadium shows that this method has great prospect for large and complex steel structures.
