ABSTRACT
The paper focuses on curved non linear structures with lose material, mainly addressing the problem of safety assessment of masonry bridges under static loads. This issue has a fundamental priority when developing strategies at a territorial level, because of the central importance of these constructions on the territory, especially in European countries. Starting from the observation of the complexity of the bridge infrastructure, where many structural and non-structural components interact with each other for composing the overall response to external action, an approach is outlined for accounting for the fill action in the total or partial absorption of variable loads.
