摘　　要：提出了一种新型空心索穹顶结构,以柔性管道代替传统的受拉钢索.基于索穹顶结构连续受拉、间断受压的构型特点,结构内部形成了一个连续的流体通路.新型空心索穹顶结构不仅可作为承载结构承担各项荷载,还可以作为空调管道系统充当温度调节的载体.通过冷空气的输入和流通,新型空心索穹顶结构可以实现对于室内温度的降温调节作用.对于所提出的结构构建方式,推导了热流分析的相关控制方程,并分析了热流荷载对结构承载能力的影响.随后,对新型Geiger-Levy混合型空心索穹顶结构的传热过程及其对于室内空间的降温过程进行了仿真分析.结果表明,所提出的新型空心索穹顶结构具有良好的可行性和实用性,空心索结构的构建思路有着广泛的应用前景.In this paper,an innovative hollow cable dome structure is proposed,in which conventional solid cables are replaced by flexible pipes.A continuous fluid path is formed within the structure based on the configuration characteristics of continuous tension members and discontinuous compression members.The innovative hollow-cable dome structure not only carries the normal loads as a structure,but also can be used as an air conditioning pipe system.Through the input and circulation of cold air,the hollow-cable dome acts as a temperature carrier and can adjust the indoor temperature.For the proposed structural construction approach,the governing equations related to thermal-fluid analysis are discussed,and the thermal-fluid effect on the bearing capacity of structure is analyzed.In addition,the heat transfer process and the indoor cooling process of an innovative Geiger-Levy hybrid hollow-cable dome are simulated and analyzed,which shows the feasibility and practicability of the proposed hollow cable dome structure,and further illustrates that the corresponding construction idea has a wide application prospect.
