Further application of the 1/3 oct band heavy/hard impact prediction method

Previously, the author 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. The previous paper was based on concrete structures in North America. This paper will be looking at the validity of the method on lighter weight mass timber buildings primarily located in the United Kingdom as well as traditional concrete buildings. The discuss will be focused on the accuracy of the method across several structures and describe why the method was less accurate in some applications. The primary cause of disagreement between predicted and in-situ measurements was high levels of background noise and other site conditions.
