Abstract
So far only a few attempts have been made to evaluate the liquefaction resistance from a ductility view point. The authors propose a new concept to evaluate the ductility of soil against liquefaction. This method is based on the energy dissipation capacity obtained from stress-strain relationships. This concept makes it possible to evaluate the liquefaction strength against big earthquakes like the 1995 Hyogoken-Nambu earthquake. The energy dissipation capacity for various soils were studied by using strain controlled cyclic triaxial test. To confirm the validity of the method proposed, we compare the results for Masado soil at Kobe Port Island obtained from elementary test, array observation data and seismic response analysis. Energy dissipation capacity obtained from above the three procedures shows very consistent results.
