“…The most challenging issue in this system is the construction of joints, which is the reason why this system was rarely used in structures before. But, according to the studies conducted on this subject, in recent years, its construction became more possible (Shen et al ., ); however, it may cost more. Various structures have been built using this tubular system all over the world, especially in china.…”

SUMMARY 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.
