Abstract
Ground vibrations generated during a large structural demolition event can be potentially damaging to nearby structures or sensitive equipment. In this paper, an approach for the prediction of the ground vibration induced by a large free-falling heavy weight is proposed based on both measured and collected data. A series of field ground vibration measurements were performed relative to the dynamic motions induced by free-falling heavy structural elements during demolition of a generating plant in the upper Midwest, USA. Using this information and the collected data, correlations between the measured PPV and normalized distance from the impact source with various ground impact energy were developed. Subsequently, an empirical PPV estimation method is suggested. This methodology will be useful in estimating dynamic effects induced by very large demolition events; especially where existing structures are located in close proximity to the impact site.
