Analysis of the Scipan 3 debris throw data using the Klotz group approach
conference paper
The Klotz Group has recently developed an engineering tool (KG-ETool) for the prediction of debris throw from reinforced concrete structures. The tool is based on state of the art knowledge, and available debris pick-up data from a number of trials. With the help of this data, relations have been obtained for the initial distributions of debris mass, velocity and launch direction, as a function of the loading density. In combination with trajectory calculations and the source function theorem, the model can be used as a prediction tool.
Whenever new data becomes available the relations are updated. This strengthens the experimental basis and increases the reliability as a prediction tool.
Recently the SciPan 3 trial has been carried out, which consisted in the detonation of 27 tonnes of TNT in an operating-type building. An important objective was to determine the debris characteristics for three wall types. The loading density in this trial exceeded that of the trials that currently form the basis of the KG-ETool. The SciPan 3 data have been used to check the validity of the distributions towards the high loading density regime. This paper describes the results and illustrates the potentials of the approach to analyse experimental data in a consistent way. The capabilities of the KG-ETool to predict the debris density observed in the SciPan 3 trial have also been illustrated.
