| 摘 要： | 国家标准《烟囱设计规范》GB50051-2002首次纳入了钢烟囱设计内容,对钢烟囱稳定计算也作出了相应的规定,但在非弹性屈曲情况下,其规定内容还不够完善。现将国内外关于圆柱壳局部屈曲计算规定进行归纳、分析和比较,并对各种计算方法进行评估,以确定钢烟囱局部稳定计算的依据。

| Abstract: | It is the first time that the design of steel chimney is added in the National Standard Code for Design of Chimneys（GB50051-2002）.Although the relevant provisions of stability calculation of steel chimney are also included,for the inelastic buckling,the provisions are not perfect.In this paper the calculation provisions on partial buckling stress of cylinder shell in domestic and oversea are concluded,analyzed and compared.All kinds of calculation method are estimated to determine the calculation basis of partial stability of steel chimney. |
