Abstract

Abstract

In recent years, steel-structure cooling towers have been widely used in thermal power generation systems due to their lightweight yet high-strength, excellent seismic performance, and short construction period. According to their structural characteristics, there are currently two main types of cooling towers: the hyperbolic tower and the cylinder-frustum tower. Different from the hyperbolic tower type, which features a continuous surface with negative Gaussian curvature, the cylinder-frustum tower type consists of surfaces with zero Gaussian curvature at both ends. Additionally, the tower body exhibits distinct geometric abruptions. The differences in force characteristics and static behavior caused by different tower types are not yet clear. Therefore, using the numerical simulation method, a static behavior analysis was conducted on cylinder-frustum and hyperbolic steel cooling towers with different heights and structural systems. The differences in the static behavior of the two tower types were compared in terms of force transmission characteristics, structural deformation, and bearing capacity.
