Abstract

Bridges and infrastructure systems, due to their inherent vulnerability, are at risk from ageing, fatigue and deterioration processes due to aggressive chemical attacks and other physical damage mechanisms. The detrimental effects of these phenomena can lead over time to unsatisfactory structural performance under service loadings or accidental actions and extreme events. The current condition ratings of stocks of existing bridges and infrastructure networks indicate that the economic impact of structural deterioration is exceptionally high and emphasise the importance of maintenance and repair of structurally deficient bridges. To deal with these problems, bridge design criteria and methods need to be revised to account for a proper modelling of the structural system over the bridge life-cycle by taking the effects of deterioration processes, time-variant loadings, maintenance actions and repair interventions into account. Relevant advances have been accomplished by the scientific community and engineering profession in the design, assessment, monitoring, maintenance and management of sustainable and resilient bridge structures and infrastructures. These advances have been presented and discussed at The Sixth International Conference on Bridge Maintenance, Safety And Management (IABMAS 2012). The extended versions of several selected papers presented at IABMAS 2012 and invited papers are published in this special issue. We hope that this collection of papers will represent a valuable reference for scientific research and engineering applications in the fields of design, assessment, monitoring and maintenance of bridges and infrastructure networks.
