During an earthquake, a bridge crane may be
subjected to multiple impacts between crane wheels and rail. In order
to model such phenomena, a timehistory dynamic analysis with a
multiscale approach is performed. The high frequency aspect of the
impacts between wheels and rails is taken into account by a Lagrange
explicit eventcapturing algorithm based on a velocityimpulse
formulation to resolve contacts and impacts. An implicit temporal
scheme is used for the rest of the structure. The numerical coupling
between the implicit and the explicit schemes is achieved with a
heterogeneous asynchronous timeintegrator.
