摘　　要：近些年来,国内外学者对烟囱结构的竖向地震作用展开了深入的研究,取得了丰硕的成果。本文简要介绍了国内外关于烟囱结构竖向地震作用的计算方法,包括竖向地震作用系数法、振型分解法、纵波应力法、行波分析法、半有限元-半解析法、简化计算法、冲量法等,并对存在的问题以及今后的研究方向提出了自己的看法。The research of vertical earthquake action on chimney has been the focus of attention in recent years, and many thorough explorations have been done for that. The computational method of vertical earthquake action on chimney structure home and abroad is summarized in this paper, which contains vertical earthquake coefficient method, longitudinal wave stress method, traveling wave method,finite element - analytical method, simplified computation method , impulse method and so on. Finally, the problems and prospects of the research are discussed and the aspects for further research are recommended.
