本文利用空间杆系有限元法，对采用边桁架支撑的单层柱面正交异型网壳进行内力分析；
Using finite element method, this paper investigates the static behavior of cylindrical orthogonal single-layer lattice shell structures supported by fringe truss.
目前，对其研究仅限于支承于刚性边梁及边桁架的正交柱面网壳的静力特性及几何非线性稳定性能。
At present, researches are only limited to the static behavior and geometrically nonlinear stability of cylindrical orthogonal supported on the rigidity roof beam or fringe truss.
