Time-Dependent Reliability Analysis of Existing Double-Curvature Bridge Strengthened with Augment Section Method

Abstract

The reliability of existing double-curvature bridge strengthened with augment section method is put forward based on time-dependent reliability theory. The concerned statistical parameter is taken by using the finite element software. First-order second-moment method is used to evaluate the reliability indexes which estimate the working state of the structure. Combined with a practical example, the time-dependent reliability is illustrated.
