Robustness analysis of bridge when exposed to train collision due to derailment

In English

Författare

Summary, in English

This paper considers evaluation of structural robustness for a multi-span concrete bridge crossing multiple rail tracks, in particular the effect of extraordinary exposures on the bridge system. A case study is performed investigating the bridge system’s response to a train collision caused by derailment in an area near the bridge supports. The probability of such an event occurring is estimated from derailment statistics on the railway net. An examination of subsequent propagating actions is carried out based on mechanical and structural considerations. Conclusions drawn here concern the issues of low probability exposures with high con-sequence and possible strategies for increasing overall robustness of these types of bridges.
