在过去的六十年里,人们深入地研究了正圆柱形张拉整体结构和球形张拉整体结构,但对环形张拉整体结构的研究却很少见.本文对一种新型的环形张拉整体结构进行了初步的分析.首先介绍了这种环形张拉整体结构的拓扑,然后总结了该结构的找形步骤,并给出了一个初始预应力解析解算例,最后提出了一种以环形张拉整体结构作为环梁的新型索穹顶体系,分析了其结构性质.本文工作可为环形张拉整体结构的进一步研究和应用提供参考.
In the past sixty years, people have deeply studied the whole structure of the cylindrical cylindrical tension and the overall structure of the spherical tension, but the research on the overall structure of the annular tension is rare.In this paper, a new type of annular tension The overall structure of the structure is analyzed.Firstly, the topology of the annular tensioned monolithic structure is introduced, and then the form-finding step of the structure is summarized. An example of the initial analytical solution of prestressing force is given. Finally, The annular tensioned monolithic structure is used as a new cable dome system with ring beam and its structural properties are analyzed.The work in this paper can provide reference for the further research and application of the annular tensioned monolithic structure.
