In this report, results from full scale experimental investigation of ground shock loading on concrete slabs are presented. Steel reinforced concrete slabs with nominal compressive strength of 30 MPa were subjected to ground shock from buried bombs. Both the free field behavior and the interaction with the structure have been studied. Simple equations were used to analyze results from experiments, considering deformations and velocity of concrete slabs as well as pressure and impulse loading on the structure. These expressions are based on Drake-Little's semi-empirical equations of the behavior of free field ground shock propagation. A comparison between the measured and the calculated values for the free field pressure shows a poor agreement. The experimental behavioral of the structure shows good agreement with the calculations.
