Wind driven power plant-structural support

A structural support system for a wind driven power plant includes a plurality of circular support frames that are supported relative to a stationary foundation by support columns. The support frames are mounted coincident with and spaced along a support-system longitudinal axis with each frame having a circular inner and a circular outer support ring. Axially directed stringers are connected to and extend between respective inner and outer support rings with associated stiffners to provide a structurally enhanced framework for supporting wind driven power plants. The support columns are preferably hinged to the foundation to permit the columns to be fabricated at ground level and pivoted into an upright position for connection to the associated support frames to provide the completed structure.
