The Performance of Helical Pile under Cyclic Load Using 3D-Finite Element Analysis [PDF]

open access: yesEngineering and Technology Journal, 2022
Helical piles are a kind of foundation that can withstand compression, tension, and lateral stresses. However, this kind of pile was utilized extensively globally for almost 25 years. Its behavior, particularly in Iraq, is uncertain and frightening.

Review of torque models for offshore helical piles [PDF]

open access: yesE3S Web of Conferences, 2020
Helical (or screw) piles, sometimes defined as anchors, are a piled system consisting of one or multiple helices welded along the shaft. Piles are installed by applying a torque to the shaft.

Axial load testing of helical pile groups in glaciolacustrine clay [PDF]

open access: yes, 2018
The behaviour of helical pile groups has not previously been experimentally investigated through field testing. In the present study, field compressive load tests of 2 Ă 2 helical pile groups and single piles were conducted in a glaciolacustrine clay in

Use of Pile Driving Analysis for Assessment of Axial Load Capacity of Piles [PDF]

open access: yes, 2012
Driven piles are commonly used in foundation engineering. Pile driving formulae, which directly relate the pile set per blow to the capacity of the pile, are commonly used to decide whether an installed pile will have the designed capacity.

Temperature response functions (G-functions) for single pile heat exchangers [PDF]

open access: yes, 2013
Foundation piles used as heat exchangers as part of a ground energy system have the potential to reduce energy use and carbon dioxide emissions from new buildings. However, current design approaches for pile heat exchangers are based on methods developed

Helical pile installation for offshore renewable energy exploration in clay seabed

open access: yes, 2022
Offshore wind and wave energy exploration are moving from shallow waters with fixed foundations to deep waters with floating devices. Helical pile has the potential to be used as both shallow water foundations and deep water anchors due to its ‘quiet ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
