冷却塔是一种应用于电力、化工等行业的大型构筑物,以往多采用钢筋混凝土薄壳结构.随着冷却塔建设规模不断增大,钢结构在大型冷却塔的结构选型中得到越来越多关注.针对钢结构冷却塔提出了一种由带支撑三角形网格构成的新型结构体系,对其布置方式、构件类型、工作原理、节点构造等进行了详细介绍,通过算例考察了结构体系的内力分布规律、刚度指标、稳定性等受力性能.分析表明,该新型钢结构冷却塔在结构层面受力性能良好,能充分发挥构件的力学性能,节点构造简单,自重轻,具有良好的技术经济指标,适合工程应用.
Cooling tower is a large structure used in electric power, chemical industry and other industries, in the past more use of reinforced concrete shell structure.With the cooling tower construction scale is increasing, the structure of the large cooling tower in the steel structure selection more and more More attention.For the steel cooling tower proposed by the triangular structure with a triangular structure of the new structure of the system, its arrangement, the type of components, working principle, node structure, etc. are described in detail through an example study of the structural system The internal force distribution law, the stiffness index and the stability etc. The analysis shows that the new steel cooling tower has good mechanical properties at the structural level, which can give full play to the mechanical properties of the components, the node structure is simple, light weight, good Technical and economic indicators, suitable for engineering applications.
