摘要
在理想预应力设计的基础上,对张弦梁结构的施工阶段和正常使用阶段的预应力损失进行了研究;对不同类型的预应力损失提出了相应的分析与补偿方法,并结合已建工程,采用顺序循环法,探讨了钢束的分批张拉损失,可供工程设计者参考。
Based on ideal prestress design for beam string structures, the prestress losses caused by various factors during the construction and normal service stages are studied in this paper. Besides, the corresponding methods of analysis and compensation to different prestress losses have also been provided. The prestress loss of tension in batches of cables is discussed using the method of sequential cycle and combined with practical engineering. The conclusions obtained are useful to designers.
