A three‐dimensional nonlinear dynamic finite‐element method (FEM) was applied to evaluate the ultimate behavior and failure modes of reinforced concrete (RC) slabs subjected to soft impact loads. In order to propose a practical impact‐resistance evaluation method for RC slab structures, computer graphics (CGs) were used as a visualization technique to simulate impact‐failure behavior of RC slabs until postfailure range was reached on the analytic results during impact loading. Immune algorithms are combined with a three‐dimensional nonlinear dynamic FEM analysis for the purpose of proposing the design of RC slabs subject to soft impact loads. The results give evidence that presents complicated failure modes, and immune algorithms can be applied to the design of RC slabs effectively.
