中文摘要：

介绍了柯以特理论,在讨论了壳体临界荷载和敏感度、缺损的类型,并简单地回顾上个世纪60年代以来普遍采用的平衡路线跟踪方法的原理的基础上,提出基于广义稳定的概念、屈曲的定义及其数学描述的屈曲路线跟踪方法.通过分析,讨论了影响网壳结构屈曲类型及分枝荷载的因素,为空间格构结构中常用的网壳结构设计临界荷载值的确定提出了建议.

英文摘要：

Widely used buckling analysis of shells is studied uninterruptedly in the study on the structural buckling analysis. Thanks to different structural behavior in the reticulated structures with different geometry, behavior of single-layer reticulated structures is similar to that of continuum shells. Thus, it is significant to grasp buckling analysis of shells. The authors expound the concept of buckling analysis of shells, which is well suited for reference in the buckling analysis of single-layer reticulated shells.
