Analysis
Summary
:
The reassessment was carried out in order to quantify the value of additional traffic load information, i.e. the case study was driven by research interests. Three different options for load modelling were analysed. As reference case, the Eurocode LM1, intended for design of new structures, was used. This was compared to LM1 adjusted with a reduction factor from earlier studies, and a site specific load model determined from WIM data. For all three options, a simulation-based reliability analysis was carried out. Two critical failure modes were identified from prior information and corresponding limit states were formulated. Assumptions for the random variables were object specific when possible and from recommendations otherwise. A value of information analysis was performed with input from the reliability analyses and consequences in terms of both bridge owner and user costs. The study demonstrates the benefits of using WIM data when making maintenance decisions.
