Description
<p>This study aims to examine how changes in load resistance capacity of a prestressed concrete bridge (PC bridge) influence on their modal properties. Static loading test was carried out under step-by-step loading until failure. In addition, forced vibration tests were carried out along the static loading test in order to assess the changes in the modal properties of the PC bridge with different health conditions. Energy performance calculated by load-displacement relation is used in order to estimate the structural performance of the PC bridge. Observations showed strong relationships between 2nd bending modal frequency and the level of structural performance. This indicates the usefulness of the 2nd bending mode in vibration-based bridge health monitoring for PC bridges.</p>
