Research Abstract

Seismic response analysis on 286 sites is made under 11 earthquake motions showed that earthquake motion indices except displacement are largest in equivalent linear analysis, then total stress truly nonlinear and effective stress analyses.
Applicability of frequently used stress-strain model such as the hyperbolic and the R-O models are examined by using 482 cyclic shear deformation characteristics test data. The R-O model shows less applicability at large strains than the hyperbolic model. Considering this, a new stress-strai model which uses only the reference strain and the shear strength is proposed.
A new test method is developed in order to reproduce in-situ stress state and loading condition during earthquakes. Test results under K0 site condition showed somewhat different cyclic shear deformation charactetistics compared with conventional test result under isotropic stress conditions.
