Shear-wave velocity (V-s) offers a means to determine the seismic resistance of soil to liquefaction by a fundamental soil property. This paper presents the results of an 11-year international project to gather new V-s site data and develop probabilistic correlations for seismic soil liquefaction occurrence. Toward that objective, shear-wave velocity test sites were identified, and measurements made for 301 new liquefaction field case histories in China, Japan, Taiwan, Greece, and the United States over a decade. The majority of these new case histories reoccupy those previously investigated by penetration testing. These new data are combined with previously published case histories to build a global catalog of 422 case histories of V-s liquefaction performance. Bayesian regression and structural reliability methods facilitate a probabilistic treatment of the V-s catalog for performance-based engineering applications. Where possible, uncertainties of the variables comprising both the seismic demand and the soil capacity were estimated and included in the analysis, resulting in greatly reduced overall model uncertainty relative to previous studies. The presented data set and probabilistic analysis also help resolve the ancillary issues of adjustment for soil fines content and magnitude scaling factors. DOI: 10.1061/(ASCE)GT.1943-5606.0000743.

Stability Charts for the Collapse of Residual Soil in Karst DRUMM, Eric C.; Akturk, Oezguer; Akgün, Haluk; Tutluoğlu, Levend (American Society of Civil Engineers (ASCE), 2009-07-01) Collapse of the residual soil over bedrock cavities often occurs during construction in karst terrain, particularly when the thickness of the residuum is reduced during excavation. Even if an estimate of the strength of the residual soil is known, uncertainty with respect to the size/geometry of the subterranean voids makes a detailed analysis difficult, and straightforward methods to check the stability are needed. In this study, numerical analyses were performed to develop a stability chart expressed in t...
Soil Uncertainty and Its Influence on Simulated G=G(max) and Damping Behavior Sett, Kallol; UNUTMAZ, BERNA; Çetin, Kemal Önder; Koprivica, Suzana; Jeremic, Boris (American Society of Civil Engineers (ASCE), 2011-03-01) In this paper, recently developed probabilistic elastoplasticity was applied in simulating cyclic behavior of clay. A simple von Mises elastic-perfectly plastic material model was used for simulation. Probabilistic soil parameters, elastic shear modulus (G(max)) and undrained shear strength (s(u)), needed for the simulation were obtained from correlations with the standard penetration test (SPT) N-value. It has been shown that the probabilistic approach to geo-material modeling captures some of the importan...
Probabilistic Model for the Assessment of Cyclically Induced Reconsolidation (Volumetric) Settlements Çetin, Kemal Önder; Wu, Jiaer; Kammerer, Annie M.; Seed, Raymond B. (American Society of Civil Engineers (ASCE), 2009-03-01) A maximum likelihood framework for the probabilistic assessment of cyclically induced reconsolidation settlements of saturated cohesionless soil sites is described. For this purpose, over 200 case history sites were carefully studied. After screening for data quality and completeness, the resulting database is composed of 49 high-quality, cyclically induced ground settlement case histories from seven different earthquakes. For these case history sites, settlement predictions by currently available methods o...
Geotechnical rock-mass evaluation of the Anamur dam site, Turkey Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01) This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
Nonlinear shear mass participation factor (r(d)) for cyclic shear stress ratio evaluation Çetin, Kemal Önder (Elsevier BV, 2004-02-01) Most methods for assessment of in situ seismic soil liquefaction potential require evaluation of the earthquake-induced cyclic shear stress ratio (CSR). Estimates of the in situ CSR can be developed directly, using dynamic response analyses, but it is common in 'simplified' analysis methods to develop estimates of the in situ CSR using empirical relationships. Unfortunately, the most widely used existing empirical relationships are based on limited response analyses and do not take full advantage of current...
