Road Bridge LCC –RAMSHEEP and reliability analysis with impact of overloading on bridge service life

Abstract In the framework of the Horizon Europe project SETO we investigated the integration of the RAMSHEEP and reliability analysis into bridge asset management and life cycle cost analysis with special emphasis on the impact of overloading of vehicles on bridge service life and availability in the context of an ageing bridge stock. For this we conducted an extensive investigation into bridge costs for construction, rehabilitation and operation, different performance functions and impact of rehabilitation measures. Based on the age distribution and standardized bridge life cycles we investigated current challenges regarding investment needs and possible strategies to ensure a reliable, available and safe bridge network based on the bridge network of regional roads in the province of Styria, Austria.
