The Performance of Bridge 'Systems': the Next Frontier for Design and Assessment

The performance of bridges, as an essential consideration in design and assessment, is examined, and the limitations of BS 5400 in this respect are highlighted. It is concluded that matters such as a varying design life, effects of corrosion, the importance of the bridge in the infrastructure network, the degree of redundancy in the structure, and interactions with bridge users, need to be taken into account. A new approach is proposed in which each bridge is treated as a component SYSTEM within the infrastructure SYSTEM for both design and assessment. P.R. Head
