Uplift Capacity of Plate Anchors in Sloped Clayey Ground

Undrained uplift capacity of deeply embedded strip anchors in non- uniform soil

This paper presents new theoretical predictions of the undrained uplift capacity of deeply embedded inclined strip anchors in a soil stratum with a linear variation of strength with depth. Rigorous bounds on the theoretical uplift capacity are presented using upper and lower bound limit analysis. The effects of the strength gradient on the normalised uplift capacity and the predicted failure me...

Uplift Response of Strip Anchors in Sand Using Fem

The load displacement relationship of shallow rigid strip anchors embedded in sands and subjected to uplift pressures has been examined by using the finite element method. The soil medium is modeled as a linear elastic-perfect plastic material following Mohr-Coulomb failure criterion and an associated flow rule. The computed load displacement response is presented in non-dimensional form. The u...

A Study on Load Capacity of Horizontal and Inclined Plate Anchors in Sandy Soils

Foundations of structures which are subjected to uplift loading require anchoring systems to resist pullout loads. Such anchors can be broadly classified as gravity anchors, pile anchors and plate anchors. Plate anchors can be circular, square or strip in shape. The loading applied on plate anchors can be vertical, inclined or horizontal depending on the anchor orientation. In this study, vario...

Capacity of Anchors in Structural Connections

Modelling the Pullout Capacity of Marquee Ground Anchors Using Neurofuzzy Technique

Marquees are temporary light structures that are connected to the ground by tensile anchors to resist forces imposed by wind acting on the structure. Failures of such structures are not rare and have resulted in deaths and tens of thousands of dollars of damage. Consequently, an accurate estimation of the ultimate pullout capacity of ground anchors is essential; however, current methods for est...
