Numerical simulation of reinforced concrete slabs under missile impact

다국어 초록 (Multilingual Abstract)

This paper presents a numerical analysis of reinforced concrete slabs under missile impactloading. The specimen used for the numerical simulation was tested by the Technical Research Center ofFinland. LS-DYNA, commercial available software, is used to analyze the model. The structuralcomponents of the reinforced concrete slab, missile, and their contacts are fully modeled. Included in theanalysis is material nonlinearity considering damage and failure. The results of analysis are then verifiedwith other research results. Parametric studies with different longitudinal rebar ratios, shear bar ratios, andconcrete strengths are conducted to investigate their influences on the punching behavior of slabs under theimpact of a missile. Finally, efficient designs are recommended.
