Full-scale tower section test

A full scale cross-section of the Hexcrete tower will be constructed and tested at the NEES Multi-Axial Subassemblage Testing (MAST) Laboratory in Minnesota. Service level and extreme loads will be applied to test the tower’s designed strength capacity. Precast concrete members will be provided by Coreslab Structures of Omaha.

Fatigue test on connections

A single panel, two column section of the wind tower will be tested under fatigue loads at the Iowa State University (ISU) structures laboratory. The test will ensure that the connection and material strengths are adequate in reaching target fatigue load values while incurring minimal damage to the structure.
