摘要：

The response process, failure modes and damage parameters of a double deck steel box girder subjected to internal blast loading of vehicle bombs (TNT equivalent 200 kg~1500 kg) were simulated by using the ALE (Arbitrary Lagrangian Eulerian) multi-material fluid-solid coupling arithmetic. In the simulation, three typical blast locations on the lower deck were considered. The results show that: the failure modes and damage parameters have a clear correlation with the TNT weight and blast location, and the explosion locations have strong effects on the damage degree of steel trusses. Stiffening ribs can restrict the crack in its vertical direction. The damage effects will be intensified by the restriction of the box-shaped girder. Some useful measurements were also proposed which can help engineers in bridge designing and protection consideration against possible explosion events. ©, 2015, Chinese Vibration Engineering Society.
