Abstract: Field testing is valuable for evaluating existing bridges. It allows the owner to reduce the conservatism of analytical rating methods and safely rate the bridge for higher loads. Many factors not considered in design ...

Abstract: To achieve consistent levels of safety over the bridge inventory, consideration should be given to the ultimate capacity of the system. Although multispan, longitudinally redundant bridges show significant reserve capacity ...

Abstract: Interstate 80 (I-80) through Wyoming carries a large volume of cross-continental trucks and large energy-industry trucks compared to many other states. Moreover, frequent weather closures position trucks side-by-side and ...

Abstract: This paper evaluates the accuracy and ease of use of 12 of the most promising models for the shear resistance of transversely stiffened steel I-girders. Several models that are well established in civil engineering practice ...

Abstract: With the advent of HPS495W steel, hybrid I-girders have again become advantageous in bridge design. Unfortunately, the use of tension field action is not permitted in determining the shear resistance of hybrid girders in ...

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 ...

Abstract: This paper presents summary recommendations pertaining to new AASHTO procedures for simplified inelastic design of steel I-girder bridges. First, key developments are summarized that lead to the proposed inelastic design ...
