Abstract:

The researchers carried out parametric finite element analyses (FEA) and field monitoring to develop improved guidelines for the widespread use of lean-on bracing applications in Texas bridges. Researchers instrumented and tested two existing bridges with lean-on bracing. Strain and displacement measurements from the completed bridges and existing data from a lean-on bridge during construction were used to validate FEA models. The validated modeling procedures were applied to a parametric study to evaluate the behavior of bridge systems with various lean-on bracing layouts. Additionally, design equations were derived resulting in improved accuracy and streamlining of the design process. The revised design procedures are summarized and demonstrated with accompanying examples.
