摘　　要：在MSC．Patran有限元软件中用梁单元建立单层肋环型圆顶的几何模型,对采用3种常用截面和不同数量约束的单层肋环型圆顶进行了静力学分析．根据分析的结果,计算出各截面尺寸对变形、应力的灵敏度．对分析结果和灵敏度进行比较得到影响单层肋环型圆顶静力性能的因素和影响程度．所得到的结论对该类圆顶的设计和优化提供依据．The single-layer lattice dome geometry model is established by using beam elements in the FE software MSC. Patran. The dome is analyzed for three different sections and different number of constraints. According the results, the sensitivity of the dimension of the section to the stress and deformation is calculated, the static characteristics of the dome and its influence factors are obtained.
