Axial response and material efficiency of tapered helical piles

Journal of Rock Mechanics and Geotechnical Engineering, 2021
Different techniques have been proposed to increase the bearing capacity of open-ended piles. Welding helices to the shaft and tapering the pile shaft could be used simultaneously to enhance the static and dynamic behaviors of these piles.

Shaft Resistance of Long (Flexible) Piles Considering Strength Degradation

Journal of Engineering, 2021
Soil-structure frictional resistance is an important parameter in the design of many foundation systems. The soil-structure interface area is responsible for load transferring from the structure to the surrounding soil.

Shaft resistance of bored piles in sand

Acta Geotechnica
Abstract This work proposes an analytical method for the evaluation of the shaft load–settlement behaviour for bored piles in sandy soils. Key assumption is that the pile shaft response can be described through a simple law employing the initial (elastic) stiffness and the ultimate resistance.

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

, 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
