摘要
鄱阳湖模型试验大厅交叉张弦桁架结构预应力索介绍结构特点和制作、张拉过程中应该注意的问题,提出了张拉过程中的调整和应急措施,并采用数学模型对张拉过程的位移和应力进行了分析。
The steel roof of Poyang Lake Model Test Hall is an intersecting truss string structure. This paper introduces the structural characteristics, fabrication method and key point of tensioning of the prestressed string, puts forward adjusting and emergent measures for tensioning construction, and uses mathematical model to analyze displacement and stress during tensioning construction.
