1 -g shaking table tests were performed in order to study the seismic behavior of laterally braced sheet pile walls retaining cohesionless soil. The dynamic pressures, backfill accelerations and wall displacements were measured on a 65 cm high model wall under input accelerations ranging between 0.06g and 0.3 8g. The 3 mm thick wall was fixed at three levels. Data acquisiton components consisting of dynamic pressure transducers, accelerometers, displacement transducers, signal conditioning board and a data acquisiton card were used throughout the study. Incremental dynamic pressures and corresponding lateral thrusts, point of application of the resultant, dynamic and permanent wall deflections, residual pressures, backfill acceleration amplifications were calculated from the stored data. Surface settlements at the soil-wall interface were also recorded. Effect of number of cycles on the lateral thrust and point of application of the resultant were investigated. The results were compared to the available analytical methods and other model experiments.

A numerical study on response factors for steel wall-frame systems
Arslan, Hakan; Topkaya, Cem (Wiley, 2010-11-01)
A numerical investigation was undertaken to evaluate the response of dual structural systems that consisting of steel plate shear walls and moment-resisting frames. The primary objective of the study was to investigate the influence of elastic base shear distribution between the wall and the frame on the global system response. A total of 10 walls and 30 wall frame systems, ranging from 3 to 15 stories, were selected for numerical assessment. These systems represent cases in which the elastic base shear res...
The effect of infill walls on the seismic behavior of boundary columns in RC frames
Fenerci, Aksel; Binici, Barış; Ezzatfar, Pourang; Canbay, Erdem; Ozcebe, Guney (2016-03-01)
The seismic behavior of a 1/2 scaled, three-story three-bay RC frame with masonry infill walls was studied experimentally and numerically. Pseudo-dynamic test results showed that despite following the column design provisions of modern seismic codes and neglecting the presence of infill walls, shear induced damage is unavoidable in the boundary columns. A finite element model was validated by using the results of available one-story one-bay frame tests in the literature. Simulations of the examined test fra...
A numerical study of solidification and viscous dissipation effects on polymer melt flow in plane channels
Tutar, Mustafa; Karakuş, Ali (Walter de Gruyter GmbH, 2013-04-01)
The combined effects of solidification and viscous dissipation on the hydrodynamic and thermal behavior of polymer melt flow during the injection process in a straight plane channel of constant cross section are numerically studied by considering the shear-rate and temperature-dependent viscosity and transient-phase change behavior. A numerical finite volume method, in conjunction with a modified form of the Cross constitutive equation to account for shear rate, temperature-dependent viscosity changes and a...
A numerical study on the dynamic behaviour of gravity and cantilever retaining walls with granular backfill
Yıldız, Ersan; Özkan, M. Yener; Department of Civil Engineering (2007)
Dynamic behaviour of gravity and cantilever retaining walls is investigated by finite element method, incorporating the nonlinear elasto-plastic material properties of soil and seperation of the wall and backfill. Two dimensional finite element models are developed employing the finite element software ANSYS. The wall is modelled to rest on a soil layer allowing translational and rotational movements of the wall. Soil-wall systems are subjected to harmonic and real earthquake motions with different magnitud...
A Large Eddy Simulation study of the bed shear stress distributions around isolated and multiple groynes
Constantinescu, G.; Köken, Mete; McCoy, A. (2008-12-01)
Large Eddy Simulation is used to investigate the main coherent structures playing a role in the erosion process (e.g., horseshoe vortex system forming around the base of the groynes, eddies shed in the separated shear layer) and the associated bed shear stress distributions around isolated and multiple groynes placed in straight channels. For isolated groynes we investigate the flow at conditions corresponding to the start of the scouring process (flat bed) and to its end (equilibrium scour bathymetry). Als...
