Concrete foundations for supporting towers and other structures under heavy cyclical loads are described. Some or all of the major concrete components, such as the beams and the hubs, that form the foundation are fabricated off-site and then transported to the intended use site for the foundation. The concrete components can be fabricated as pre-cast segments, sections, or pieces, with the pre-cast segments then being assembled in the field at the use site to form each component, and the components then being assembled together to form the foundation. In one embodiment, the beams used in the foundation may have a box-girder construction. 115-. (canceled)16. A wind turbine foundation , comprising:a center hub that is configured to be secured to a tower of a wind turbine;a plurality of pre-cast concrete beams secured to and projecting radially outward from the hub, each of the pre-cast concrete beams is formed as a box girder construction.17. The wind turbine foundation of claim 16 , wherein each of the pre-cast concrete beams is formed from a plurality of pre-cast concrete beam segments that are assembled together.18. The wind turbine foundation of claim 17 , wherein there are three of the pre-cast concrete beam segments for each of the pre-cast concrete beams.19. The wind turbine foundation of claim 17 , wherein at least two of the pre-cast concrete beam segments are hollow from an inner end to an outer end thereof.20. The wind turbine foundation of claim 16 , wherein the center hub is formed from pre-cast concrete.21. The wind turbine foundation of claim 16 , wherein the center hub is formed from a plurality of pre-cast concrete hub segments that are assembled together.22. The wind turbine foundation of claim 21 , wherein there are four of the pre-cast concrete hub segments.23. The wind turbine foundation of claim 21 , wherein the pre-cast concrete hub segments fit together into a ring shape.24. A wind turbine foundation claim 21 , comprising:a center hub that is ...
