PROBABILISTIC METHODS FOR IMPROVED BRIDGE ASSESSMENT

The paper demonstrates through three practical applications the benefits that can be obtained by using the modern probabilistic methods of reliability analysis, either directly for assessing a bridge or indirectly for refining the assessment criteria used in conventional methods. The first example relates to the development of a bridge specific assessment live load for a long span bridge in South Asia which helped to save considerable strengthening costs. The second example demonstrates the use of reliability methods combined with Bayesian updating techniques for the assessment of aN Rc slab viaduct in the UK which had shown inadequate shear capacity. The anAlysis confirmed the need for strengthening but helped to keep the viaduct open to traffic in the interim period with some restrictions. The last example relates to the use of reliability methods for maintenance planning of Midland Links viaducts in the UK which provided a manageable repair programme for the deteriorating RC crossbeams spread over a number of years without compromising public safety.
