Static and Buckling Analysis of Highway Bridges by Finite Element Procedures
The research focused on the application of finite element computer programs to complex bridge structures which may be idealized as an assemblage of one and two-dimensional elements. Assemblages of these elements are able to effectively represent three-dimensional structural behavior for a detailed determination of stresses and deflections for a wide range of highway structures. Demonstration analyses were performed on two highway bridges under the action of dead and live loads including prestressing forces. The influence of severely skewed supports, curvature along the bridge center line, lateral bracing and transverse diaphragms and concrete placing sequences on the structural response was studied. In addition, a buckling analysis of an interior steel girder was made in an effort to gain insight into bracing and stiffener requirements. A preliminary investigation of the influence of thermal stresses caused by daily variations in temperature was undertaken.
