提出了一种用于结构可靠性分析的增量加载方法，并进行了说明。随着连续的构件达到极限，结构逐渐被拉开拉链，直到结构整体倒塌。这种方法的一个固有优点是，除了计算平均值之外，还可以提取结构能力的方差，计算量最小。该方法考虑了不同类型的构件行为，如脆性和延性，不同的结构布置，如并联和串联构件，以及结构单元之间的统计和力学相关性。
An incremental loading approach to structural reliability analysis is presented and illustrated. The structure is progressively "unzipped" as successive members reach their capacity until overall structural collapse occurs. An inherent advantage of this approach is that the variance of structural capacity is extracted in addition to the mean value, with a minimum of computational effort. The method accounts for different types of member behavior such as brittle and ductile, different structural arrangements such as members in parallel and series, and statistical and mechanical correlation between structural elements.
