Effect of rate of loading on uplift capacity of a model pile in
clay.

In this study, the Influence of rate of loading on uplift capacity
of piles in day is experimentally investigated. Uplift capacity
tests were conducted under different loading rates using a model
steel pile having an outside diameter of 30 mm. In addition,
consolidated undrained triaxial tests were performed under the
same loading rates used in the uplift capacity tests. Experimental
results showed an increase in undrained shear strength of the
tested soil with the increased rate of loading. Furthermore, the
uplift capacity of the model pile was found to increase as the
loading rate Increased. The relationships between loading rate,
and both the undrained shear strength and the uplift capacity can
be represented by a straight line on a log-log plot Theoretical
bearing capacity was calculated based on the undralned shear
strength measured in the triaxial tests and compared with the
measured uplift capacity under the same loading rate.
