Improvements to the 1/3 octave band heavy-hard impact prediction method.

Previously, the authors presented a 1/3 octave band heavy/hard impact prediction method based on force pulse measurements from a drop tower. Since then, we have been applying the method with a variety of success. Previous papers presented on this topic were based on above grade applications in North American buildings. This paper will be looking at a slab-on-grade construction in the United Kingdom. This paper will be focused on the accuracy of the method and possible modes of error. It is shown that improved methodologies to measure the force pulse increased the accuracy of the prediction. [ABSTRACT FROM AUTHOR]
