Abstract

Finite element analyses of several statically-, seismically-, and dynamicallyinduced liquefaction flow failures suggest that existing relations to estimate the yield strength ratio of contractive, saturated sandy soils may be conservative. Herein, we propose tentative revised relations for estimating yield strength ratio using normalized penetration resistance. These relations are based on available laboratory data from triaxial compression, torsional shear/triaxial compression, direct simple shear, and ring shear tests on isotropically- and anisotropicallyconsolidated specimens. We use the finite element analysis results from the case histories for preliminary verification of the proposed updated relations for yield strength ratio.
