| 摘 要： | 根据国内张弦结构项目屋盖的关键受力构件布置方式与支承边界平面水平投影线的组合进行了屋盖结构分类,从屋盖支座设置方式和索初始预拉力入手,分析了张弦桁架结构屋盖在不同支座形式时不同索初始预拉力对下部支承结构的作用力及屋盖结构的力学响应。分析表明,为充分实现张弦屋盖的自身控制功能,降低张弦桁架空间屋盖与下部支承结构的静力相互作用影响,应从屋盖结构总体系的层面综合考虑进行张弦桁架空间屋盖结构的布置,合理确定索初始预拉力,从而正确选择结构静力设计计算模型。

| Abstract: | Roof structure system is classified based on the arranging mode of key load-bearing members and horizontal projection lines of roof support border, which were used in domestic spatial string structure projects.The force loaded by spatial truss string structure roof to its under support and the mechanical response of roof itself with different roof brackets and different string initial tensile force are analysed.According to the analysis,in order to achieve a good function of self-control,as well as decrease... |
