Reliability Assessment of Bridge Column under Accidental Impact

Abstract:

It is shown that alternative procedures for probabilistic assessment of design impact forces given in EN 1991-1-7 leads to similar results. The impact forces are up to three times greater than the recommended indicative values given in the main text of EN 1991-1-7. Provided that no other safety measures are undertaken, the structures designed for recommended lower bound of impact forces may have insufficient reliability. Application of the upper limit of impact forces should be recommended for key bridges where the bridge columns are situated near road intersections or in the adverse configuration of the terrain.
