Soils are inherently variable and heterogenous in both vertical and horizontal directions. The variability in soil parameters can be represented by a statistical distribution (such as normal, lognormal etc.) having a mean and a standard deviation. In addition, variability can be defined in terms of spatial correlation length (i.e. the scale of fluctuation) which is relevant in random finite element method (RFEM). The variability of soil parameters can be considered in the probabilistic risk assesment and reliability in geotechnical engineering by using these methods. The first purpose of this study is to determine the variability and spatial correlation length of the near-shore sea-bottom soils at a site in southern coast of Turkey. Based on the data obtained from 23 boreholes on the seabed, the general characteristics of the marine soils in this area are presented, and spatial correlation length in the vertical direction is evaluated based on the SPT-N blowcounts. The second purpose of the study is to demonstrate the effects of soil variability and spatial correlation length on the settlement and bearing capacity; for which random finite element softwares, RSETL2D and RBEAR2D are used, respectively. The results show that considering the variability of the soil significantly influences the settlement and bearing capacity

A study for the development of seismic design specifications for coastal structures Gözpınar, Erdem; Yalçıner, Ahmet Cevdet; Ergin, Ayşe; Department of Civil Engineering (2003) An evolving design philosophy for port structures in many seismically active regions reflects the observations that: -The deformations in ground and foundation soils and the corresponding structural deformation and stress states are key design parameters. -Conventional limit equilibrium-based methods are not well suited to evaluating these parameters. -Some residual deformation may be acceptable. Performance-based design is an emerging methodology whose goal is to overcome the limitations present in convent...
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...
Solution of one dimensional transient flow in composite aquifers using stehfest algorithm Bakar, Ürün; Önder, Halil; Department of Civil Engineering (2010) In this study, piezometric heads in a composite aquifer composed of an alluvial deposit having a width adjacent to a semi-infinite fractured rock are determined. One dimensional transient flow induced by a constant discharge pumping rate from a stream intersecting alluvial part of the aquifer is considered. Parts of the aquifer are homogeneous andisotropic. Equations of flow, initial and boundary conditions are converted to dimensionless forms for graphical presentation and the interpretation of results ind...
The effect of basin edge slope on the dynamic response of soil deposits Cılız, Serap; Özkan, M. Yener; Department of Civil Engineering (2007) The effects of basin edge slope on the dynamic response of soil deposits are assessed by using one-dimensional and two-dimensional numerical analyses. 24 basin models having trapezoidal cross section are generated to represent different geometries (basin depth, basin edge slope) and soil type. Harmonic base motions with different predominant periods (Tp) are used in the analyses. The results indicate that, for a constant basin edge slope and a constant ratio of fundamental period of site to the predominant ...
Lateral load analysis of shear wall-frame structures Akış, Tolga; Tokdemir, Turgut; Department of Engineering Sciences (2004) The purpose of this study is to model and analyze the nonplanar shear wall assemblies of shear wall-frame structures. Two three dimensional models, for open and closed section shear wall assemblies, are developed. These models are based on conventional wide column analogy, in which a planar shear wall is replaced by an idealized frame structure consisting of a column and rigid beams located at floor levels. The rigid diaphragm floor assumption, which is widely used in the analysis of multistorey building st...
