The spatial correlation length (SCL), or the scale of fluctuation, is a parameter for describing the spatial variability of soil and one of the important parameters used in random field theory. Studies reporting the spatial correlation length based on real field data of offshore/nearshore sea bottom soils are rather limited in the literature, so in this study, the vertical spatial correlation length is determined using site investigation data from two sites of the southern coast of Turkey. Based on quite extensive data, the vertical spatial correlation length is estimated using four different autocovariance functions. The values are within typical ranges reported in the literature for similar soil groups, both onshore and offshore. It is also noted that the widely-used exponential function almost always gives the lowest value of spatial correlation length. The results of this study add to the database of spatial correlation lengths based on real data and could be useful for future studies on reliability assessment of offshore foundations using random finite element method.

Spatial probabilistic evaluation of sea bottom soil properties and its effect on foundation design Oğuz, Emir Ahmet; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2017) The spatial correlation length (SCL), or the scale of fluctuation, is a parameter for describing the spatial variability of a soil property and is one of the important parameters used in random field theory. Studies reporting the SCL of soil properties of offshore/nearshore soils are rather limited in the literature. In this study, the vertical SCL is determined using site investigation data from two nearshore and one large offshore sites in Turkish waters. In nearshore sites, a total of 41 boreholes and St...
Experimental evaluation of geomembrane/geotextile interface as base isolating system Kalpakci, V.; Bonab, A. T.; Özkan, M. Yener; Gülerce, Zeynep (Thomas Telford Ltd., 2018-02-01) The objective of this study is to evaluate the effect of the geomembrane/geotextile interface on the seismic response of small-to-moderate height structures. Three building models with first-mode natural frequencies changing between 2-4 Hz (representing two, three and four storey structures) were tested with and without the addition of geomembrane/geotextile interface using the shaking table test setup by employing harmonic and modified/ scaled ground motions. Experimental results showed that the geomembran...
Ground Motion Prediction Equations for the Vertical Ground Motion Component Based on the NGA-W2 Database Gülerce, Zeynep; Abrahamson, Norman A.; Silva, Walter J. (SAGE Publications, 2017-05-01) Empirical ground motion models for the vertical component from shallow crustal earthquakes in active tectonic regions are derived using the PEER NGA-West2 database. The model is applicable to magnitudes 3.0-8.0, distances of 0-300 km, and spectral periods of 0-10 s. The model input parameters are the same as used by Abrahamson et al. (2014) except that the nonlinear site response and depth to bedrock effects are evaluated but found to be insignificant. Regional differences in large distance attenuation and ...
Cyclic Large Strain and Induced Pore Pressure Models for Saturated Clean Sands Çetin, Kemal Önder (American Society of Civil Engineers (ASCE), 2012-03-01) Semiempirical probabilistic models are described to assess cyclic large strain and induced excess pore-water pressure responses of fully saturated clean sands. For this purpose, available cyclic simple shear and triaxial tests were compiled and studied. The resulting r(u) versus gamma, and gamma versus N databases are composed of 101 and 84 cyclic test data, respectively. Key parameters of the proposed r(u) and gamma models are defined as critical shear strain, relative density, effective confining stress, ...
Integrated nonlinear regression analysis of tracer and well test data Akın, Serhat (Elsevier BV, 2003-08-01) One frequent observation from conventional pressure transient test analysis is that field data match mathematical models derived for homogeneous systems. This observation suggests that pressure data as presently interpreted may not contain details concerning certain reservoir heterogeneities. On the other hand, tracer tests may be more sensitive to heterogeneous elements present in the reservoir because of the convective nature of the flow test. In this study, a possible improvement of conventional pressure...
