| 摘 要： | 板锥网壳网络是一种新型的空间结构，它是在板锥单元和常规的双层刚壳结构的基础上组合形成的一种新型结构形式，具有良好的技术经济效益和建筑视觉效果。本文在对这类结构有限法分析的基础上，根据板锥网壳结构的构成特点，应用广义协调元的基本思想，对这类结构进行了分析，给出了这类结构广义协调元分析的基本公式。分析表明：广义协调元法适宜于板锥网壳结构的受力性能分析，广义协调元固有的简便，高效和可靠的特性，将会使结构分析得到更为可信和可靠的论证。

| Abstract: | Plate-cone reticulated shell is a new pattern space structure. In this paper based upon the analysis of this structure by regular finite elements, the geometric nonlinear properties of this structure with generalized conforming finite element were analyzed. The basic formulas for analysis was given, and the computer programs were compiled. From the computation, it is found that the generalized conforming element is a kind of simple, high-efficiency and reliable elements. Its property of simplicity, high-efficiency and reliability will achieve better results for the analyses of structure. |
