Due to structural degradation, the performance of concrete bridges may degrade with time and result in catastrophic consequences. A novel approach is developed for evaluating time-variant reliability multi-girder considering effects load-carrying mechanism redundancy. By three failure modes at both component system levels, a new indicator proposed quantitatively load elastic distribution plasti...

At present, the main methods of bridge condition assessment are reliability analysis and analytic hierarchy process method. Robustness, as a measure structural ability to maintain performance after occurrence variations, can provide different perspective based more on property itself. Although robustness has been mainly used in design optimization against progressive collapse extreme events, it...
