Fluid impact tests on reinforced concrete beams with rectangular or circular transverse reinforcement were modeled and simulated using explicit finite element analysis software, LS‐DYNA. The mid‐span displacements were measured and compared with the results of simulations. The objective was to test the accuracy and fidelity of the numerical modeling and simulation approach and to confirm that damage caused by fluid impact on the beams can be estimated with a reasonable accuracy over a wide range of impact velocity.

Thirty‐two reinforced concrete beams were tested under static and fluid impact loads. Hoop (rectangular) and spiral transverse reinforcement of various configurations were used to confine the specimens. The objectives were to observe the effect of shape of beams and configuration of confinement reinforcement on the impact resistance, and to estimate the limiting fluid velocity that causes total failure.
