Report on Dynamic Fracture of Concrete (ACI 446.4R-04) 2

Report on Dynamic Fracture of Concrete (ACI 446.4R-04)

Description Impact, explosions, and earthquakes impose dynamic effects on concrete structures. Impact loading on a parapet can occur if it is struck accidentally by a crane. Seismic loading produces significant strain rates in concrete shear-walls and other lateral force-resisting elements. Explosive loading, due to accidental detonation of industrial vapor clouds or terrorist bombing, produces high
