Effect of combined translation and torsion on undrained

Uplift capacity of plate anchors has been the focus of numerous studies, because anchor plates are designed for pull‐out in normal operating conditions. However, the response of plate anchors under 6‐degrees‐of‐freedom loading caused during extreme loading conditions is poorly understood.

Evaluating scale effects and bearing portions in centrifuge

2021/4/12Helical anchors are bearing elements that can resist uplift loads by a combination of shaft and helical plate bearing. The application of helical piles as offshore wind turbine foundations has recently become interesting. However, large size of such structures limits the possible physical modeling in a geotechnical centrifuge. In the current study, the limits of physical modeling concerning

Scale effect in centrifuge tests of helical anchors in sand

2016/11/22The uplift capacity of a single-helix anchor is the sum of the helix bearing resistance plus the shaft resistance; therefore, recommendations to avoid the grain-size effect of previous model tests on plate anchors and on regular piles appear to be reasonable for

(PDF) Experimental Investigations on Behaviour of

Plate anchors, direct embedment anchors, helical anchors, grouted anchors, and anchor piles are some of the classification of ground anchors which are commonly used. The most popular type of anchor among them in resisting the pullout loads is plate anchor, since they provide an economic alternative to gravity and other embedded anchor foundations.
