Geothermal energy piles (GEPs) are an environmentally friendly heat exchange technology that dualizes the role of structural foundation pile for load support and in meeting building heating/cooling need. Energy loops made from high-density polyethylene, which allow carrier fluid circulation, fitted into elements to extract or inject store soil surrounding pile. This paper reports results a nume...

This paper presents the experimental analysis that was conducted on small-scale 1g physical models of piled raft foundation structures with a group 2 × piles in loose sand. The purpose to reduce settlement raft. test program included twelve experiments, three which were alone and nine rafts at pile distances 3d, 4d, 5d lengths 10d, 20d, 40d, where d is diameter. results show current conventiona...

A parametric study was carried out to study the behavior of offshore anchor piles under mooring forces in dense sand using a three dimensional (3-D) finite element model (FEM). The Mohr–Coulomb plastic model has been used to model the soil, and has been calibrated based on the centrifuge tests discussed in a Ph.D. thesis (published by Ramadan in 2011). The selection of model parameters and comp...

During the building reconstruction with floors addition, there is a need to evaluate frame and foundation soil bearing capacity, especially if are deviations from design parameters. As result of field numerical studies, we determined basic change patterns in stress-strain state 12-storey load-bearing structures monolithic reinforced concrete due uneven pile deformation. We also found influence ...

In order to understand the load sharing and settlement reduction behaviour of piled raft resting on soft clay, 1g model tests were conducted on small-scale models. The parameters studied were the effect of pile length and number of piles. The load settlement behaviour obtained from the tests has been validated using simplified method (Polous & Davis). Equivalent pier concept of Poulos and Davis...
