In the present work, analysis of concrete pavements using ANSYS software has been attempted. is a finite element method-based software. The slab modeled with solid 45 brick and spring elements for soil. Analysis was carried out wide range load soil combination. as “Winkler type” represented by elastic springs their stiffness derived from modulus sub-grade reaction. influence any particular base...

The study presents the investigation of elastic behavior soil in optimal design continuous foundations according to rigid solid case. For investigation, optimization algorithm that can find section and reinforcement details has been developed. developed uses one well-known meta-heuristic methods named artificial Bee Colony method design. Winkler spring hypothesis (analytic solution) is used cal...

We consider non-stationary free and forced transverse oscillation of an infinite taut string on the Winkler foundation subjected to a discrete mass–spring system non-uniformly moving at given sub-critical speed. The speed is assumed be slowly time-varying function. To describe non-vanishing we use analytic approach based method stationary phase multiple scales. oscillator characterized by parti...

This thesis develops analytical solutions for estimating the bending moments and axial loads in a buried pipeline due to ground movements caused by tunnel construction in soft ground. The solutions combine closed-form, analytical solutions for tunnel-induced, free-field ground deformations in a plane orthogonal to the heading (Pinto and Whittle; 2001) with Winkler models for pipe-soil interacti...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

OBJECTIVES To develop and test an optimal ensemble configuration of two complementary probabilistic data matching techniques namely Fellegi-Sunter (FS) and Jaro-Wrinkler (JW) with the goal of improving record matching accuracy. METHODS Experiments and comparative analyses were carried out to compare matching performance amongst the ensemble configurations combining FS and JW against the two t...
