摘要
对于变形控制要求极高的预应力梁,在设计中较难把握的是对混凝土收缩和徐变产生的梁变形和预应力损失的控制。本文目的在于借助成熟的有限元分析软件,通过对大跨度预应力钢筋混凝土梁进行仿真分析,及时地为工程设计和现场实体试验提供经济、准确的依据和指导。
For beams being accurate to deformation control , t o control the deformation and prestressing losses from concrete shrinkage and cr eep is the key point in design. With mature finite element analysis software the proper suggestions could be provided for engineering design and field prototype experiment of prestressed concrete beams.
