A computationally simple method to calculate the static response of arbitrarily shaped shallow foundations subjected to eccentric loading is proposed. A theoretical relationship to estimate the area beneath the foundation that is contact with the load bearing support is developed. This relationship yielded an equation to calculate rocking angle of an arbitrarily shaped foundation under any load eccentricity. Consequently, a simple theoretical model capable of simulating the effects of material and geometrical nonlinearities on the response of arbitrarily shaped shallow foundations subjected to monotonically increasing eccentric and inclined load is developed. The theoretical results are justified by using the results of three available sets of experiments from the literature. Then the parametric analyses of shallow foundations subjected to eccentric loading are performed. It is observed that the proposed theoretical method yields reasonably accurate results in terms of moment-rotation response of shallow foundations.

Mathematical modelling of decoration peak associated with dragging point defects situated selectively at the kink chain with special references to hydrogenated BCC and FCC metals
Ogurtani, TO (1997-01-01)
The set of nonlinear differential equations that describes the kink chain oscillating in an atmosphere of continuously distributed paraelastic or isotropic point defects and, in addition, decorated by a dragging point defect at the midpoint, is solved numerically after introducing a novel scaling and renormalization procedure. The internal friction coefficient obtained indicates the existence of two separate peaks, the decoration peak and the parent peak, which are directly related to the localized point de...
EXTENSION OF THE RESIDUAL VARIABLE METHOD TO PROPAGATION PROBLEMS AND ITS APPLICATION TO THE WAVE-EQUATION IN CYLINDRICAL COORDINATES
AKKAS, N; Tokdemir, Turgut (Elsevier BV, 1992-08-03)
Consider a partial differential equation with cylindrical coordinates describing a dynamic process in an infinite medium with an inner cylindrical boundary. If an analytical solution to the problem is not possible, then one resorts to numerical techniques. In this case it becomes necessary to discretize the infinite domain even if the solution is required on the inner cylindrical surface or at a limited number of points in the domain only. The residual variable method (RVM) circumvents the difficulty associ...
The finite element method for MHD flow at high Hartmann numbers
Nesliturk, AI; Tezer, Münevver (Elsevier BV, 2005-01-01)
A stabilized finite element method using the residual-free bubble functions (RFB) is proposed for solving the governing equations of steady magnetohydrodynamic duct flow. A distinguished feature of the RFB method is the resolving capability of high gradients near the layer rep-ions without refining mesh. We show that the RFB method is stable by proving that the numerical method is coercive even not only at low values but also at moderate and high values of the Hartmann number. Numerical results confirming t...
A simplified non-linear procedure for buildings with shear walls
TEKELİ, Hamide; Atimtay, Ergin (Thomas Telford Ltd., 2015-01-01)
A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to bot...
Improving the strength of additively manufactured objects via modified interior structure
Al, Can Mert; Yaman, Ulaş; Department of Mechanical Engineering (2018)
This thesis study provides an approach to improve the durability of additively manufactured parts via modified interior structures by considering the stress field results from tensile loading conditions. In other words, the study provides an automated method, i.e., implicit slicing method, which improves the strength of the parts with infill structures modified according to the quasi-static Finite Element Analysis (FEA) results under tensile loadings, automatically. The parts which are used throughout the w...
