Predicting response of reinforced concrete slabs under low-velocity impact

A two-degrees-of-freedom (2-DoF) dynamic model is proposed to predict the response of reinforced concrete (RC) slabs subjected to low-velocity impact. In this model, the slab stiffness is calculated based on its dynamic load–displacement curve, which is built using moment–curvature analysis and crit...
