摘要
根据风洞实验以及国外相关的规范或规定,我国现有规范对钢筋混凝土烟囱体形系数的取值存在偏小的嫌疑。本文通过某电厂双管钢筋混凝土烟囱风洞试验结果,综合了各国规范进行计算比较,引出了国内规范中烟囱体型系数取值以及风干涉效应的相关问题。
According to wind tunnel tests and foreign relative codes, nowadays, shape factor of reinforced concrete chimney as GB is probably too low .Through the tunnel tests result of a power plant double reinforced concrete chimney, comparing and calculating codes of other countries, this paper points out relative questions of shape factor sampling and wind interference effect in GB.
