Abstract

Effective design method for response spectra of a single degree of freedom (SDOF) structure taking into consideration liquefaction of ground layer and ground improvement by the compacting method is presented. This method con- sists of the 2D effective stress analysis of surface ground layers, the simulating analysis of the sand compaction pile method and the seismic response analysis of a SDOF structure. The renewal natural period of the ground due to the ground im- provement and the natural period of a SDOF structure are used as two key parameters for evaluating response spectra. Results of numerical computation sh
