ACI ITG-9R-16 PDF Download

The Report on Design of Concrete Wind Turbine Towers, also known as ACI ITG-9R-16, focuses on the design of concrete towers for land-based wind turbines that exceed 325 ft (100 m) in height. The report highlights the advantages of using concrete towers over round steel tubular towers, including cost reduction, increased stiffness, and improved service life performance.

The report provides guidance on various aspects of concrete tower design, such as construction alternatives, design criteria, design methodologies, and preliminary design recommendations. It emphasizes the importance of close coordination with the turbine supplier during the final tower design process. While concrete towers designed for maximum wind forces can be suitable for preliminary design, the report highlights the need for checking all loads, especially considering fatigue and dynamic effects from wind and turbine operations.

Furthermore, the report emphasizes the significance of understanding fatigue requirements during preliminary design to ensure the validity of connection design during the final checks.
