双曲冷却塔温度效应分析
Study on the thermal effects of hyperboloidal cooling towers
摘要
Abstract
Researches were initiated for the hyperboloidal cooling towers. Based on the comparisons and combinations with dead weight effects and wind effects, the functions of thermal effects for struc- ture design were elaborated. Related specifications and detailing requirements in China, British, Ger- many codes were compared as well. Results show that the initial temperature of cooling tower shells hardly have influences on the thermal effects, and the huge illogical internal forces in top and bottom edge shells are due to the missing of temperature parameters of cornice and columns which give rise to a temperature constrain condition. The circumferential moment is also a controlling internal force in structure design, and the contribution from thermal effects is much bigger than that from wind effects. Compared with British and Germany codes, the minimum circumferential reinforcement in China code is much smaller, the strength safety must be satisfied according to structure analysis but not only constructed reinforcement, the minimum reinforcement ratio should he increased.关键词
