Natural draft steel hyperbolic cooling towers: Optimization and performance evaluation
Demand for efficient and economical hyperbolic cooling towers has driven engineers toward designing tall and lightweight towers, specially, in regions with high‐seismic ground motions. An effective way to achieve this goal is using steel cooling towers. Also, by using tubular diagonal grid (Diagrid) system as the structural system, the weight of cooling tower will reduce, significantly. Therefore, in this investigation, a steel hyperbolic cooling tower is modeled with Diagrid system. A linear analysis, under dead and wind load, is performed on several systems with different angles of Diagrids to reach the optimal angle of grids. Furthermore, the effect of stiffening rings on the cooling tower is examined, and it is observed that the use of stiffening rings makes the tower lighter. And, by performing nonlinear time history and stability analyses, the behavior of the cooling tower is investigated under strong earthquakes, and it is represented that the system shows very good performance during strong earthquakes.
