ABSTRACT:
A method for stiffening a wind turbine tower employing fingerplate assemblies on flangeless joints between adjacent tubular tower sections. The method includes limiting the intercan gap between adjacent end surfaces of the tower sections at the flangeless joints and selecting a number of fingerplates to fasten each flangeless joints to limit distortion. Establishing dimensions for the fingerplates may further minimize localized tower distortion. Selecting a material for the fingerplate with a lower Young's modulus than a material for the tubular section also results in reduced localized tower distortion. Attaching a coverplate to a top tubular section limits tip displacement for the tower.
