Research on Assessment Methods of Load-Bearing Capacity of Existing Bridges

This paper makes an in-depth research on Assessment Methods of Load-bearing Capacity of Highway Bridge (Ministry of Communications of The People’s Republic of China, 1988) and makes a conclusion on assessment methods. Combined with current bridge inspection technology, it points out the limitations and shortcomings of the methods, and proposes the direction of assessment of existing bridge load-bearing capacity.

Method Analysis

Advanced methods of reliability analysis based on simulation techniques of Monte Carlo type in combination with nonlinear finite element method analysis represent effective tools for reliability assessment of the existing bridges. Knowledge of current level of load bearing capacity of the bridge and its development in the coming years while meeting the required level of reliability may help to schedule the bridge maintenance systematically and efficiently and/or it can facilitate decision-making on the manner and extent of its reconstruction. The paper briefly introduces methodology of probabilistic determination of the load bearing capacity of bridges with respect to the ongoing deterioration processes in time. The methodology is applied to determine the current level of load bearing capacity of a reinforced concrete parapet beam bridge built and for its estimation in the coming years until the end of the theoretical service life of the structure.
