The Ultimate Uplift Capacity of Foundations

Canadian Geotechnical Journal, 1968
The ultimate uplift capacity of foundations with special reference to transmission tower footings is evaluated. A number of model uplift tests made by the authors and by others were studied and compared with full-scale tests. These tests showed a complex failure mechanism which varied with the depth of the foundation.

Vertical Uplift Capacity of Horizontal Anchors

Journal of Geotechnical Engineering, 1994
The method of characteristics coupled with a log-spiral failure surface was used to develop a theory for vertical uplift capacity of shallow horizontal strip anchors in a general c-phi soil. Uplift-capacity factors F(c), F(q) and F(gamma), for the effects of cohesion, surcharge, and density, respectively, have been established as functions of embedment

Seismic uplift capacity of inclined strip anchors

Canadian Geotechnical Journal, 2005
Uplift capacities of inclined strip anchors in soil with a horizontal ground surface are obtained under seismic conditions. Limit equilibrium approaches with a logarithm-spiral failure surface and pseudostatic seismic forces are adopted in the analysis.

Uplift Capacity of Group Piles in Sand

Journal of the Geotechnical Engineering Division, 1976
The purpose of this paper is to present some recent laboratory model test results to study the variation of uplift capacity of pile groups with various shape, size, and pile spacings in loose sand. However, it may be pointed out that for all of these tests the length-to-diameter ratios of the piles were kept constant, and other variables such as soil ...

Uplift Capacity of Z‐Purlins

Journal of Structural Engineering, 1991
Roof systems constructed using cold-formed steel components, i.e., Z-shaped purlins and interconnected roof panels, have become a very popular form of construction. This roof system is used extensively for single-story commercial and industrial buildings in the United States.

Uplift Capacity of Model Piles Under Oblique Loads

Journal of the Geotechnical Engineering Division, 1976
Structures such as transmission towers and mooring systems for ocean surface or submerged platforms with pile foundations are subjected to uplifting forces. A limited amount of work is found in literature regarding the theoretical analysis and experimental determination of the uplift capacity of pile foundations in granular and cohesive soils.

Uplift Capacity of Axially Loaded Piles in Clays

International Journal of Geomechanics, 2011
The present study aims at determining the uplift capacity of axially loaded piles in clays whose undrained cohesion increases linearly with depth. With the application of the axisymmetric static limit analysis approach, proposed recently by the writers, the variation of the nondimensional uplift factors with respect to changes in the embedment ratio ...

Effects of K0 and Overconsolidation on Uplift Capacity

Journal of Geotechnical Engineering, 1992
This paper presents the results of experimental and theoretical studies on the determination of the overconsolidation ratio and its effect on the uplift capacity of foundations, with special reference to screw anchors installed in sand. Based on data reported in the literature, a semi-empirical relationship is proposed to relate the uplift capacity of ...

Uplift Capacity of Pile Anchors in Cohesionless Soil

Deep Foundations and Geotechnical In Situ Testing, 2010
An analysis of uplift capacity of pile anchors in cohesionless soil is proposed in which Kotter’s equation is employed to obtain the distribution of soil reaction on the axisymmetric failure surface, assumed to be the frustum of a cone with a characteristic angle of inclination with the pile-soil interface.

Uplift capacity of an under-reamed pile foundation

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2015
Designing foundations to resist uplift forces is becoming of increasing concern, and is especially prevalent in the design of lightweight steel frame buildings or on sites with residual soils. However, little academic research has investigated under-reamed piles, instead focusing almost exclusively on anchor plates.
