Abstract—Under active stress conditions, a rigid cantilever retaining wall tends to rotate about a pivot point located within the embedded depth of the wall. For purely granular and cohesive soils, a methodology was previously reported called minimization of moment ratio to determine the location of the pivot point of rotation. The usage of this new methodology is to estimate the rotational sta...

The earth retaining structures frequently represent key elements of ports and harbors, transportation systems, lifelines and other constructed facilities. Earthquakes might cause permanent deformations of retaining structures and even failures. In some cases, these deformations originated significant damages with disastrous physical and economic consequences. For gravity walls, the dynamic eart...

Failure loads of sheet pile having various profiles such as U, Z and Omega/Hat under compression was carried out by using equations strength materials compared the failure load modes Euler’s buckling, torsional buckling due to yielding. Compared flexure finite element analysis. Sheet can be analyzed a unit cell for simplified For selecting with omega/Hat section profile containing one eight num...

The vertical component of ground motions is known to cause severe damages certain structures. Long span cable-stayed bridges are among those vulnerable structures due their high mass and cables that take no compression. In this paper, the earthquake effects on several have been investigated using 3-D nonlinear time history finite element analyses. Different main lengths, pylon shapes pylon/deck...

Diffusion-driven flow arises when a stably stratified fluid is bounded by an inclined wall. For a stratified fluid in an inclined fissure, in which fluid is confined to a gap between two inclined parallel walls, the flow field is determined by the gap width and the angle of inclination. When the gap width is much wider than the buoyancy layer thickness, the problem reduces to that of a semi-inf...
