TLDR
Although semi-open H piles have been widely used, geometric effects (GEs) on H-shaped piles in consolidating ground subjected to negative skin friction (NSF) and downdrag are still not well understood.Abstract:

Long-term thermo-mechanical behaviour of energy piles in clay
TL;DR: In engineering practice, energy pile foundations are often designed for the lifetime of the building as mentioned in this paper, and thermal exchange between a pile and the surrounding soil depends on the annual energy needs of a building.

Closure of "Termination Criteria for Jacked Pile Construction and Load Transfer in Weathered Soils"
TL;DR: In this article, two steel H piles were instrumented, installed at a weathered soil site, and load tested to improve termination criteria for pile jacking and to better understand the behavior of jacked piles.

Numerical investigation of pile-head load effects on the negative skin friction development of a single pile in consolidating ground
Jiunn-Shyang Chiou,Wun-Tao Wei +1 more
TL;DR: In this article, the influence of structural loading (pile-head loading) on the development of negative skin friction in friction single piles and friction-end-bearing single piles in consolidating ground was investigated.

Negative Skin Friction on Piles: State of the Art
TL;DR: In this article, the authors present the state of the art relating to negative skin friction on piles and present the key problems that lie ahead for future research related to NSSF on pile and pile groups.

Mechanism of Downdrag for Floating H-Pile Subjected to Surcharge
TL;DR: In this paper, the downdrag mechanism for floating H-piles subjected to surcharge loads was investigated by performing three-dimensional numerical comparative analyses, and the constitutive models and model parameters were calibrated using a centrifuge test.

The strength and dilatancy of sands
TL;DR: In this paper, the strength and dilatancy of 17 sands in axisymmetric or plane strain at different densities and confining pressures are collated, and the critical state angle of shearing resistance of soil which is shearing at constant volume is determined experimentally within a margin of about 1°, being roughly 33° for quartz and 40° for feldspar.
On the generalized stress-strain behavior of wet clay
TL;DR: The theory of the three-dimensional stress-strain behavior of WET CLAYs was introduced by BURLAND as discussed by the authors, who showed that WETCLAYs are subject to three dimensions of stress and strain.

Unified dynamic shear moduli and damping ratios of sand and clay
Isao Ishibashi,Xinjian Zhang +1 more
TL;DR: In this article, the experimental data on dynamic shear moduli and damping ratios of various soils including non-plastic sands to highly plastic clays are collected and reanalyzed and brought into simple unified formulas.

Catalogue of scaling laws and similitude questions in geotechnical centrifuge modelling
Jacques Garnier,Christophe Gaudin,Sarah M. Springman,Patricia J. Culligan,D. Goodings,D. Konig,Bruce L. Kutter,Ryan D. Phillips,Mark Randolph,Luc Thorel +9 more
TL;DR: In this paper, the scaling laws and similitude conditions of geotechnical centrifuge models were investigated. But only a few studies were devoted to the questions and concerns about scaling laws.
