Disclosed are apparatus and corresponding methodology for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Different types of concrete are used between upper and lower sections of the stacked cylinders. The lower section uses reinforced concrete while the upper section used ultra high performance fiber reinforced concrete.

The method of claim 1, wherein said plurality of staves form a conical skirt, said conical skirt operating to distribute a tower load to said ring foundation pad. 18. The method of claim 1, wherein said method comprises providing a plurality of external ballasts, said external ballasts configured to add additional dead load to said ring foundation pad. 19. The method of claim 1, wherein at least some of said plurality of staves comprise plural subcomponents. 20. A method for constructing a base structure for a support tower, comprising: constructing a ring foundation pad;positioning a transition piece above such ring foundation pad;positioning a plurality of staves around such transition piece, each of such plurality of staves respectively comprising a top portion and a bottom portion, such bottom portion of each such stave being wider than such top portion thereof;respectively securing such bottom portion of each of such plurality of staves to such ring foundation pad;respectively securing such top portion of each of such plurality of staves to such transition piece;selectively including conduits in such plurality of staves;extending at least one tendon through a conduit disposed in one of such plurality of staves, wherein such conduit is a U-shaped conduit extending partially through the length of such stave; andapplying tension to such at least one tendon to secure such stave to such base structure. 21. The method of claim 20, wherein such conduit comprises a U-shaped conduit having respective first and second legs connected by a horizontal portion, wherein such first leg extends through a first stave of such plurality of staves and such second leg extends through a second stave of such plurality of staves. 22.
