Numerical analysis of group effect on dragload on piles subjected to negative skin friction [PDF]

Journal of Engineering Research - Egypt, 2022
In this paper, the group effect on dragload on pile group subjected to negative skin friction is studied. The effect of pile spacing, pile location in a group and pile number is studied using finite element program PLAXIS 3D. Single pile, 2x2 pile groups

Formulas for Uniaxial Capacities of Tetrapod Bucket Foundations Considering Group Effects in Undrained Clay

Applied Sciences, 2022
Suction bucket foundation is a novel and cheaper foundation used in marine structures, such as offshore wind turbines, breakwater and oil platforms. Compared with a single bucket foundation, tetrapod bucket foundations can bear larger loads because of ...

Semimechanistic models to relate noxious stimulation, movement, and pupillary dilation responses in the presence of opioids

CPT: Pharmacometrics & Systems Pharmacology, 2022
Intraoperative targeting of the analgesic effect still lacks an optimal solution. Opioids are currently the main drug used to achieve antinociception, and although underdosing can lead to an increased stress response, overdose can also lead to ...

Histopathology of the broad class of carbon nanotubes and nanofibers used or produced in U.S. facilities in a murine model

Particle and Fibre Toxicology, 2021
Background Multi-walled carbon nanotubes and nanofibers (CNT/F) have been previously investigated for their potential toxicities; however, comparative studies of the broad material class are lacking, especially those with a larger diameter. Additionally,

Static and Dynamic Response of Micropiles Used for Reinforcing Slopes

Applied Sciences, 2021
To study the static and dynamic response of micropile-reinforced slopes, static model tests and shaking table tests were performed. The failure modes, the pile-slope interaction, the displacement, and the static/dynamic earth pressure distributions were ...

Analysis of Bearing Characteristics of Energy Pile Group Based on Exponential Model

Energies, 2021
Energy piles are an emerging energy technology for both structural and thermal purposes. To support structure load, piles are always used in groups with raft; however, the cost and complexity of field tests and numerical modelling limits the research on ...
