Thermal Movements of Two Steel Composite Bridges: A Case Study

摘要

The goal of this research was to better understand the behavior of bridge systemssubjected to temperature loading, and secondly, model two Wyoming Department of Transportation (WYDOT) bridges that are currently experiencing distress initially attributed to temperature effects. To address the first objective, finite element-based parametric studies were performed to address the sensitivity of the geometry, bearing location and stiffness, and joint gap/locking. The model used is characteristic of a medium-span bridge. The second objective was addressed by creating models of the two distressed bridges and reporting the response due to temperature loads. The present condition of these bridges was considered and recommendations for repairs are given.
