Abstract
A hybrid wind turbine tower support structure that combines pultruded fiber glass composites lineals with reinforced concrete, effectively creating a low cost structure for holding large, laterally-forced-thrusts from wind turbine rotor blades. The structure is designed to be lower in installed costs then its counterpart steel support structure, yet be capable of withstanding very large thrust loads, deflecting-under-load less than or equal to, but no more, under extreme wind loading, than its counterpart, steel support structure.
