As a part of Selected Industrial Structures subject, I was asked to deliver a project of concrete chimney, hight 115 m, built of 12 segments with the internal diameter 3.55 m. The task consisted of checking coefficient of dynamic response of a structure, second order effects, horizontal imperfections, thermal load and ovalization under wind load. The amount of steel rebars in vertical direction (primary reinforcement) was calculated as well as circumferential reinforcement due to thermal loads. The foundation reinforcement was arranged consitering forces from Chu and Afandi formula for circular and ring foundations.
