Abstract
The purpose of this study is to evaluate the feasibility of the development and application of the strain energy method for general use. The study is expected to continue with two additional phases that will develop generic strain energy, liquefaction curves as a function of the most relevant soil properties and generic strain energy demand as a function of seismicity data and a wide range of site soil data and profiles. The limited scope of the feasibility study did not permit laboratory testing for the purpose of the strain energy computation. Available laboratory data were used for this purpose.
