本文研究了短程线型球面网壳的优化问题。文中采用了矩阵位移法进行内力分析,并用迭代法按离散截面进行杆件设计。另外,用模式搜索法对这种球壳的高度及网格两个变量进行优化,得出了这种网壳在不同跨度时的最优网格与高度。还讨论了荷载的影响。 This paper studies the optimization problem of geodesic spherical lattice shells. In this paper, the matrix displacement method is used to analyze the internal forces, and the iterative method is used to design the rods in discrete sections. In addition, using the mode search method to optimize the height of the shell and the two variables of the mesh, the optimal mesh and height of the shell in different spans are obtained. The effect of the load is also discussed.
