钢筋混凝土双曲线冷却塔竖井架的优化设计

OPTIMUM DESIGN FOR VERTICAL SHAFT FRAME OF HYPERBOLA COOLING TOWER OF REINFORCED CONCRETE

采用结构力学方法，编制塔式设备竖井架通用计算程序对双曲线冷却塔竖井架进行了优化设计，研究了竖井架杆身正应力、剪应力、局部及整体稳定性、自振周期的变化规律．结果表明，１２孔断面结构是双曲线冷却塔竖井架最理想的设计．

In order to optimize the vertical shaft frame of hyperbola cooling tower of reinforced concrete, an universal program for calculating vertical shaft frames of tower installations are developed on the basis of structural mechanics. The results of comparisons of normal stress, shear stress, local and overall stability, free vibration period among five designs show that the twelve hole section is the optimum design of vertical shaft frame of hyperbola cooling tower of reinforced concrete.
