During the long-term operation of an urban railway viaduct, it is subjected to multiple cyclic loads caused by movement a vehicle. As result, fatigue life bridge should be fully considered during design process. Furthermore, structure will subject environmental corrosion for extended period time, resulting in concrete carbonization and reinforcement corrosion, which aggravates structure’s damag...

The rigorous modeling of traveling loads on bridges in a dynamic regime is not an easy task as the load contributes to structural system with its mass and damping. In this paper, simplified approach for proposed. main simplification consists neglecting mass. validity proposed checked sensitivity analysis considering few realistic case-study bridges. ranges velocity traveling-force/bridge-weight...

In the context of continuous economic growth country, engineering project investment and construction are now transforming from rough to lean. It is urgent optimize information technology, standardize management mode, improve efficiency. At same time, integration industrialization informatization requires a deep combination, field can exploit pain points management, build an intelligent system,...

Considering the recent collapses which have affected several existing reinforced concrete (RC) motorway bridges, correct maintenance interventions planning of these strategic infrastructures has acquired increasing importance to maintain a suitable safety level even in case seismic loads. One most important problems influences structural performance RC bridges is presence corrosion may affect b...

Various theories and analytical formulations were implemented exploited in the 1980s 1990s for design of bridge beams or decks curved horizontal plane subjected to out-of-plane loads. Nowadays, Finite Element Method (FEM) is a valid tool analysis structures with complex geometries and, therefore, development sophisticated not needed anymore. However, they are still useful validation FE models. ...
