摘要
针对复旦大学正大体育馆屋盖采用134根拉索与空间钢桁架和大钢拱共同组成了索-桁架-拱体系,综合考虑了各种非线性因素的影响,利用通用有限元软件,研究分析了拉索张拉顺序,据此制定了各批索的张拉施工方案。研究结果对类似工程有一定的借鉴作用。
The steel roof of Fudan Zhengda Gymnasium is a complicated pre-tensioned system made up of space truss, steel arc and 143 cables. In this paper, the general analysis software-ANSYS is used to analyze the tension process of cables in steel roof. According to the theoretical analysis results, a construction plan for tensioning of cables is proposed.
