✦ Synopsis

This paper summarizes the experience gained in the design of the Ohaaki cooling tower in New Zealand. The design was governed by the strong seismicity of the site, and unusually complex step-by-step calculations including large displacements, uplift and sliding of the foundations were performed. The analysis showed the low-energy dissipation in the plastic range offered by the diagonal supports, despite some modification of the initial design, such as the use of mild steel reinforcement in the supports. A comparison between the actual design and alternative designs for the supporting structure is also given.
