Development of strain sensor holders to be applied to the monitoring of metallic structures

ABSTRACT: The Laboratory of Structures (LABEST) of the Faculty of Engineering of Porto University (FEUP) has been engaged, in the latest years, in assessing the structural performance of several steel structures. The observed bridges and viaducts structural typology is very rich, gathering recently constructed viaducts and centenary bridges, single and multiple span decks, truss and steel plate girders, metallic and masonry piers. Figure 1 illustrates some monitored structures.
