张弦梁结构、弦支穹顶结构为两类典型的杂交空间结构,适用于大跨度的屋盖结构如航站楼、会展中心、体育场馆等。该文提出了上部结构为自由曲面网格结构的张弦体系或弦支体系等一般大跨度杂交空间结构的形状确定问题,并在以往解析分析的基础上提出了数值分析的算法和计算例题。在此基础上编制了相应程序,结合实际工程给出了计算分析例题。该文的工作可供工程设计人员和有关学者参考。 Stringed beam structure, strut dome structure for two types of typical hybrid space structure, suitable for large-span roof structures such as terminal buildings, convention centers, stadiums and so on. In this paper, the shape of general long-span hybrid space structures such as string system or chord system with superstructures as free-form mesh structure is proposed. The numerical analysis algorithms and calculation examples are proposed based on the previous analysis. On this basis, the corresponding program is compiled, and the example of calculation and analysis is given with the actual project. The work of this paper can be used as reference for engineering designers and relevant scholars.
