ABSTRACT
In the design of bridge structures, usually only seismic and wind loads are considered as dynamic loads. But sometimes accidental loads may be surcharged, for example, to bridge deck slabs because of heavy objects falling from moving vehicles at a high speed or to a bridge railing because of an automobile crashing into it at a high speed. In the case of cross-channel bridges, the basement of bridge pylons should be designed to withstand an impact force because of collision of ferries, oil tankers, and container vessels. In these cases, up until now, dynamic response analyses of modeling the structure as a single or multidegree of freedom system are usually performed. A rational impact-resistant design procedure not only for bridge and other road infrastructures but also for reinforced concrete (RC) beams/ slabs has not yet been established.
