摘　　要：考虑结构的几何非线性和材料的弹塑性,对一个K6型单层球面网壳进行稳定性分析。通过对比分析发现,此结构的弹塑性稳定承载力约为其弹性稳定承载力的50%,材料的弹塑性对不对称荷载作用下的稳定承载力的影响更显著。Considering both geometrical nonlinear and material nonlinear, a K6 single-layer latticed dome has been carried on the stable analysis. Comparative analysis shows that elastic-plastic stability critical loads is elastic stability critical loads of 50%, and material nonlinear is approximately more remarkable influence to stability critical load under the asymmetrical load.
