Abstract: Analytical methods are used to develop design values for the number of stress cycles caused by the passage of a truck across various types of spans of steel highway bridges. Vibration stresses and close truck spacings are ...

Abstract: Three transversely stiffened A572 Grade 50 steel girders were tested to obtain full moment‐rotation curves for use in the autostress design of continuous‐span bridge girders. The flange and web slendemess ratios were close ...

Abstract: Yield-interaction relationships are developed for compact, compact-flange, and noncompact sections of curved girders under combined vertical and lateral (warping torsion) moments. These relationships define the bending ...

Abstract: Fatigue evaluation and design methods were developed in a recent project for steel highway bridges. The evaluation method enables an engineer to estimate the safe remaining life of an existing bridge. The estimate of safe ...

Abstract: Inelastic design of steel girder bridges can result in beneficial material and fabrication cost savings and reduce the susceptibility of steel girder bridges to fatigue. The ability to redistribute large negative region ...
