Journal ArticleDOI
Influence of SPT Procedures in Soil Liquefaction Resistance Evaluations
TL;DR: In this paper, the authors clarified the meaning of the values of standard penetration resistance used in correlations of field observations of soil liquefaction with values of N1 measured in SPT tests.
Journal ArticleDOI
Moduli and Damping Factors for Dynamic Analyses of Cohesionless Soils
TL;DR: In this article, a simple relationship is proposed to relate the shear modulus of a cohesionless soil to a modulus stiffness coefficient, which is a soil property and depends on the characteristics of the soil, and the effective mean principal stress at any point in the soil.
Journal ArticleDOI
Standard penetration test-based probabilistic and deterministic assessment of seismic soil liquefaction potential
K. Onder Cetin,Raymond B. Seed,Armen Der Kiureghian,Kohji Tokimatsu,Leslie F. Harder,Robert E. Kayen,Robert E. S. Moss +6 more
TL;DR: In this paper, the authors present new correlations for assessment of the likelihood of initiation (or triggering) of soil liquefaction, which eliminate several sources of bias intrinsic to previous, similar correlations, and provide greatly reduced overall uncertainty and variance.
Journal ArticleDOI
Evaluation of Settlements in Sands Due to Earthquake Shaking
Kohji Tokimatsu,H. Bolton Seed +1 more
TL;DR: In this article, a simplified method of analysis is proposed for estimating probable settlements in either saturated or unsaturated sand deposits subjected to earthquake shaking, and the results are shown to compare favorably with settlements observed at six sites for which good data on settlements have been observed.
Journal ArticleDOI
Empirical correlation of soil liquefaction based on spt n-value and fines content
Kohji Tokimatsu,Yoshiaki Yoshimi +1 more
TL;DR: In this article, a critical review of field performance of sandy soil deposits during past earthquakes was conducted with special emphasis being placed on Standard Penetration Test N-values and fines content.
