Abstract : An elastic design analysis method is presented for small foundations which utilize an energy criteria. It provides a direct approach for calculating allowable loads and for estimating the design efficiency of the resulting structure. The method has the advantage of circumventing the standard method for single degree of freedom systems in first calculating the fixed base frequency, utilizing shock design spectra, and equivalent static load analyses. A sample problem is presented that shows how to establish maximum allowable equipment weight for a shock. The results are worked up in some detail to show the ease of application of this method.
