Abstract
A post-tensioning system that is configured for use with concrete wind turbine foundation designs to post-tension the foundations and reduce the amount of reinforcement steel that is needed compared to conventional non-post-tensioned, steel reinforced concrete foundation designs. In the case of an inverted T gravity foundation, the post-tensioning system described herein reduces the amount of reinforcement steel that is required by 30-40 tons.
