Load Testing & Evaluation of Two Swing Span Bridges
SDR was tasked to structurally evaluate two swing span bridges through load testing coupled with Finite Element Analysis (FEA) with the aim of removing the current load posting. The tested controlling spans comprised steel plate girder sowing span and CIP concrete slab spans. Test results revealed that, the actual performance of the test bridges is more favorable than what is estimated by design codes. Load rating of the controlling spans was revised considering test findings and FEA results, which resulted in removing the posting weight.
