摘要
对螺栓球节点网架实际工程进行了高空散装施工阶段的数值分析。指出在施工各阶段中结构的变形和杆件的内力均随施工过程而变,个别杆件的应力可能在施工中超过屈服极限或发生局部失稳;结构最危险的阶段通常是在施工阶段,因此进行施工阶段的设计验算是必要的。
This paper makes the numerical analysis on the construction stage of high dispersed erection of the bolted ball node grid based on an actual engineering, and points out that in each construction stage, the deformation of the structure and the stress of the member bars are changing along with the process of the construction, and the stress of some member bars maybe exceed the yield limit and occur the partial destabilization, and the most dangerous stage of the structure is the construction stage, so the checking calculation for the construction stage is necessary.
