A nonlinear dynamic layered finite element procedure is proposed for analysis of reinforced concrete slab structures subjected to soft impact loads. The effects of material nonlinearity, concrete plasticity, concrete element cracking and also the loading and unloading phenomena in the plastic regions are considered in the analytical procedure. The analysis is capable of predicting the ultimate behaviors as well as the impact failure modes very well. Verification of the procedure is carried out by comparison with results from tests on full-scale reinforced concrete slabs. Finally, analysis of different impact collisions into reinforced concrete handrails are carried out. The results indicate that a low loading rate would result in bending failure while the punching shear failure mode is more dominant at high loading rates.
