Introduction: A project investigating the Dynamic Resistance of Transmission Tower Footings.

Objectives: To carry out enhanced environmental modelling of full Overhead line support system fully via instrumenting a short section of line.

To carry out centrifuge modelling to expand the range of foundation and soil types currently considered, using the data collected by the environmental modelling.

To assess the appropriateness of current British Standard method for determining tower foundation uplift capacity and influence the change of industry design codes.
