Paper highlights: Dynamic response of beams with switching cracks under moving masses

This work focuses on the behaviour of damaged Euler-Bernoulli beams with any number of unilateral cracks and subjected to one or more moving masses which remain always in contact with the beam. The proposed approach is particularly important when dealing with bridges subject to moving vehicles, where cracks, local material deterioration and structural joint damages caused by environmental and loading conditions can lead to excessive deflections or unexpected bridge failures.
