摘　　要：通过结构非线性分析程序ＳＮＡＰ，对不同长度的单层柱面网壳结构进行了非对称荷载作用下的全过程稳定分析，通过变化不同的参数，考察荷载非对称分布对单层柱面网壳稳定性能的影响规律，得到了对工程设计有指导意义的结论。Based on the non linear complete process analysis program SNAP,a complete process analysis of stability behavior of single layer lattice vaults with different length is carried out.The effect of unsymmetric loading distribution to the stability behavior of single layer lattice vaults with various parameters changes is also analyzed.Some important conclusions are acquired and can be used to instruct engineering design.
