Pipe Impact on Concrete Slabs Concrete responses ranging from no damage to severe penetration were observed. There was strong interaction between pipe impact (crushing) and concrete reaction. Two different analytical methods qualified for impact on a very stiff structure were used to correlate experiment and analysis.
