摘要

摘要: 近年来,钢结构冷却塔因其轻质高强、抗震性能好、施工周期短等优点在火力发电系统中广泛应用。根据冷却塔体型的特点,目前主要有双曲线塔型及圆柱-截锥塔型2种塔型。与负高斯曲率连续曲面的双曲线塔型不同,圆柱-截锥塔型由2段零高斯曲率曲面组成,塔体有明显的几何突变,由塔型不同引起的受力特点及静力性能差异目前尚未明确。因此,采用数值仿真方法,开展了不同高度、不同体系的圆柱-截锥型及双曲线型钢结构冷却塔的静力性能分析,从传力特性、结构变形及承载能力等方面对比了2种塔型静力性能的区别。

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.
