Turbine Missile Perforation of Reinforced Concrete

Abstract

Improved empirical methods for the prediction of perforation of reinforced concrete barriers by missiles produced by turbine fracture are developed. Data from recent turbine missile tests and existing empirical methods of perforation damage analysis were collected and compared. Selected formulas were chosen for improvement. For each, modifications are proposed which result in a more accurate prediction of the occurrence of perforation of reinforced concrete barriers by missiles typical of those that might be found at nuclear power generating facilities. Also, a method is given to allow perforation analysis of reinforced concrete barriers with a thin steel plate affixed to the back face.
