摘要: 对一种大跨度叠层空腹桁架整体转换结构预应力筋不同布置方案对结构的影响进行了分析讨论,并就该种转换结构体系的预应力施加方案及预应力筋面积的初估方法提出了建议,进而可为相关工程设计提供参考。Abstract: It is analyzed and discussed that the effect on the structure of different layout schemes of the prestressed bars for an integral transfer structure with large-span laminated open-web trusses; some suggestions are proposed on initially evaluating the presstressed barsarea and the scheme of applying prestresses for this transfer structural system, which provides a reference for design of relevant projects.
