Life-cycle Assessment And Deterioration
Models For Masonry Arch Bridges

Abstract
Bridges are key elements of the rail and road network and their safe maintenance
is of strategic importance. A large proportion of bridge networks are approaching
100 years and maintenance/strengthening are becoming increasingly important
issues. Life-cycle management aims to optimise long-term budgets,
interventions, traffic, costs, environmental impact, amongst others. While
bridges are only designed for up to 120 years, they often require significant
interventions within 50 years. Masonry arch bridges have proved to be highly
sustainable long-lasting structures with low maintenance needs. While bridge
management currently has an approximately 100-year prospective, informed
long-term deterioration models and tools are required before a longer-term view
can be adapted. Long-term methodology for assessing masonry arch bridges is
discussed and deterioration models proposed for fatigue compressive and shear
loading based on laboratory tests. Initial results are considered in terms of
practical application.
Keywords: masonry arch bridges, life-cycle analysis, bridge management,
bridge fatigue, SN curves.
