In this study an effective method for nonlinear constrained optimization of shallow foundation is presented. A newly developed heuristic global optimization algorithm called Gravitational Search Algorithm (GSA) is introduced and applied for the optimization of foundation. The algorithm is classified as random search algorithm and does not require initial values and uses a random search instead ...

In the simple buildings, shallow foundations can be used to support construction above them. This foundation has various types, including type of footplate which calculated using Terzaghi equation. equation, it requires dimension parameters footing and soil material such as cohesion volume weight laboratory testing obtain it. Meanwhile, Schmertmann provides an equation bearing capacity factor i...

Structures built on sands worldwide, with shallow foundations, have experienced damage and collapse during after earthquakes. Two phenomena triggered the collapse: liquefaction phenomenon P-Δ effects. However, current research practice do not fully understand granular soil behavior effects, as proven by sum of investigations physical models, constitutive laboratory testing proposals about these...

In this paper, stability of slopes with a shallow foundation located on top including the shape of the failure mechanism is investigated in static and seismic states. This is a three dimensional problem which is analyzed two dimensionally because 3D analyses are complex and appropriate softwares are not available. The conventional method of bearing capacity evaluation of foundations on top of ...

The problem of settlement shallow foundations is among the most important ones in classical soil mechanics. And while for flexible elastic solutions are widely used, rigid rectangular where actual contact pressure distribution still unknown, approximated either analytically assuming a or semi‐empirically combining theory elasticity with experimental and/or numerical results. A third and often a...

Despite recent advancements in predicting the response of shallow strip foundations during earthquake-induced liquefaction, significant modelling–related uncertainties remain, which are focus this paper. The problem is analysed through coupled hydromechanical analyses, employing an advanced constitutive model. model calibrated based only on initial void ratio, and then validated against 6 centr...
