利用时变安全可靠度理论，对现有结构的剩余寿命进行评估，提出了对可变荷载取值进行修正的方法。
The theory of time-dependent ability is adopted to evaluate the residual service life of structure and a method is adopted to revise the variable load.
此外，根据结构的动态失效模型还可以确定油气管线结构在不同时期的可靠度以及结构的有效剩余寿命。
Furthermore, the reliability at different periods and the effective remaining life of oil and gas pipelines could also be determined with the dynamic failure model of structure.
该方法计及了各个子结构的剩余模态的作用，并能消去基本扇形的全体对接自由度，故这种精确的动力缩聚进一步提高了动态分析的效率。
It collects the residual mode contributions of various substructures, and then eliminates all interface degrees of freedom of the basic sector. Hence this accurate dynamic reduction fur...
