Rate effects on the vertical uplift capacity of footings founded in clay
Significance of output:
This work clearly identified a simple reverse bearing capacity type failure for shallow foundations in clay subject to rapid uplift. For the first time the effects of loading rate on the development of tension at the foundation/soil interface was characterised in terms of the soil strength and footing area. Further verification of this mechanism through extensive field testing has been sponsored by National Grid. This and associated publications forms the main technical developments within CIGRE for improvements to international design guidance related to tower foundations subject to rapid uplift and the incorporation of rate loading effects.
