Reliability of RC Bridge Supports Designed to Resist Heavy Goods Vehicle Collisions

In English

Författare

Summary, in English

The reliability of bridge-supporting structures to resist impacts from heavy goods-vehicles (HGV) is investigated. Probabilistic simulations are carried out to calculate the reliability index of a circular reinforced concrete column that has been designed using historical values for equivalent static impact loads provided in the Eurocode. Considerations are made for the uncertainties related to the dynamic response and resistance of reinforced concrete bridge supports subjected to vehicular impact. A general procedure is outlined for determining the dynamic resistance of the structure. As input for the impact force, results from previous probabilistic simulations of HGV impacts to road side structures were used. It is found that the design based on the codified approach does not provide adequate safety levels in the case of the structure studied. An alternative formulation for determining more appropriate values for the impact load is suggested and some discussion was given pertaining to other possible design strategies for the treatment of these types of loading situations.
