A 75 feet high multi-level structure was designed to support huge condensers in each level. A large slenderness ratio made the tower vulnerable to wind load and overturning. A three-dimensional Staad-III model was created.
A combination of live, thermal, wind, and hydrostatic loads was a governing case. The fast track nature of the project dictated a number of changes that were adhered to utilizing the flexible computer model.
