摘要：
In view of the contradiction which load effects are assumed to be both independent and completely related in load-effect combination method recommended by JCSS, and the ineffectiveness of time-interval analysis method for non-stationary load-effect process in engineering, structural reliability analysis method considering load sequence is performed. Firstly, the structural reliability analysis method under non-stationary load effect process is proposed. Secondly, the structural reliability calculation model under multi-period load considering load sequence is improved. Finally, the influence of structural damage on reliability is analyzed by cross-threshold theory, and the formula for calculating structural reliability considering non-stationary load process, loading sequence and structural damage is derived. The results showed that the method is more applicable and the calculation results are more realistic and reliable. © 2019, Editorial Department of Journal of Northeastern University.
