Protection systems against impacts of vessels on bridge supports are essential to guarantee the structural integrity of bridges and the safety of users, avoiding the ruin of supports or the collapse of parts or the entire structure of the bridge, thus guaranteeing its functionality and prolonging its service life. These structures have their specificities and the definition of the type of protection to be adopted and its sizing must consider the environment conditions of the region. In the Brazilian standardizations, there are design criteria and specifications that contemplate the navigable spans considering the width of the vessels only, which has been insufficient for navigation in the region of bridges crossing navigable channels/rivers in Pará, North Region of Brazil. In evaluating the accidents that have been taking place in Pará, it appears that these criteria are insufficient to protect bridge structures from the severe accidents that have occurred in the last 10 years. |
