Infrastructure and transportation facilities have increased rapidly over the years. This has been accompanied by an increased number of vehicle collisions with structures. This type of collisions might leads to the damage and often collapse of the structures. In Reinforced Concrete (RC) structures, columns are usually the most vulnerable members exposed to collisions. However, the existing design guidelines and provisions for protection of these members against collision of vehicles are not adequate. In particular, the desired behavior and the associated performance levels of a structure during a vehicle collision are not defined. Therefore, there is need to assess the vulnerability of struc-tures against such collisions. This paper develops probabilistic models for the dynamic shear capacity of RC columns that can be used for a performance-based design of structures such as bridges and buildings, to estimate the adequacy of a structure to sustain a collision, and to make recommendations for repair and retrofit. © 2011 Taylor & Francis Group, London.
