Field Tests of Super-Long and Large-Diameter Drilled Shaft Pile Foundations

Advances in Civil Engineering, 2020
This study investigated the compressive behaviour of super-long pile foundations with large diameters. Three 52 m, 73 m, and 83 m long piles with a diameter of 1500 mm, 1500 mm, and 1800 mm were cast and tested, respectively. Given that large loading was

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]

, 2011
In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.

Resistance factor calculations for LRFD of driven piles based on setup effects

Results in Physics, 2018
Setup effects, one of a large number of uncertainties in geotechnical engineering, can strongly enhance the bearing capacity (ultimate resistance) of driven piles after initial installation, especially for ultimate shaft resistance.

Lateral bearing capacity of large-diameter pile foundation based on hardening and softening models of side resistance

Yantu gongcheng xuebao, 2018
From the perspective of the vertical shaft resistance producing significant contribution to the lateral bearing capacity of large-diameter pile foundation, the numerical and analytical solutions are firstly established for pile shaft resisting moment per

Depth-Dependent Load-Transfer Variability in Three Ultralong Bored Piles: Evidence from Full-Scale Load Tests

Buildings
Ultralong postgrouted bored piles constructed with the same design configuration may exhibit different internal load-transfer behaviour that is not fully reflected by pile-head load–settlement curves.

Internal torsion resistance in deflected shafts

Alexandria Engineering Journal, 2017
Most of the shaft theories have based their analysis on bending moment, twisting moment or combined between them. Nevertheless, the dynamic behavior of flexural-torsional coupled vibrations in the rotating shafts is affected by the internal resistance forces due to torsion.

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.
