In recent years, the exceptional performance of steel fiber-reinforced concrete in blast and impact resistance has garnered widespread recognition, sparking considerable interest its practical application small box girders. To this end, nine groups Trinitrotoluene (TNT) explosion simulation experiments were designed with equivalent magnitudes matching those actual automobile explosions to evalu...

ABSTRACT: Bridges are structures built to overcome obstacles and allow continuity of transport routes. In the search for efficient construction systems, steel-concrete composite structures, especially box girder bridges, emerged. The American AASHTO European EN 1994-2-2 standards present design procedures this type bridge, but there still doubts about which portion concrete slab contributes eac...

Based on the theory of vehicle track coupling dynamics, the local vibration of the high-speed railway box girder is analyzed by the Finite Element Method and the model is simulated with the solid elements. Through the study of vibration characteristics of the selected 6 sensitive points, the local vibrations in different parts of the box girder are figured out. It is compared the response of th...

It has been argued that the AASHTO LRFD design code for maximum live loads on highway bridges is overly conservative. In an attempt to determine the level of conservativeness, if any, the writers developed a methodology incorporating real-time visual data collection from traffic cameras coupled with structural strain response of girder bridges. Average daily truck traffic along with frequency o...

With the development of economy and transportation, more cross-sea bridges are appearing in people’s view. However, not only subjected to repeated traffic loads but also corrosion from marine environment. In addition, steel box girder deck plate is directly vehicle loads, its welded details highly susceptible fatigue damage destruction, resulting or top plate-U rib girder. This paper based on f...
