Large mass or velocity collisions can result in substantial structural damage or collapse even though they are uncommon. They can be brought on, among other things, by wind-generated missiles, car accidents, or weaponry. The con-sequent dynamic inertial loads and the impact of the high strain rates on the material characteristics make it difficult to analyze and design for these effects. Therefore, structural engineering places a high value on any advancements made in impact resistance or dynamic analysis and design processes. For many years, experts have researched how plain and reinforced concrete reacts to impacts. This chapter elaborates dynamic and cyclic performance of FRP material.
