Three Span Bridge

Some codes of practice suggest that multi-span bridges can be safely modelled as a series of single spans provided the piers are 'stocky'. Here, LimitState:RING 2.0 - being used to rapidly explore a variety of scenarios in advance of an intrusive investigation - demonstrated that this is not always the case.

Single Span Bridge

Very short span bridges are often vulnerable to the damaging effects of excessive live loads. LimitState:RING 2.0 was here used to identify likely critical failure modes. It was found that all likely failure modes involved sliding, rather than a standard '4 hinge failure mechanism'.
