| 摘 要： | 对烟囱的震害规律进行了分析.认为地震时烟囱的破坏,竖向地震力起了很重要的作用.提出了用冲量法来计算烟囱的竖向地震作用,并以190 m 高的钢筋砼烟囱为例进行了计算.对计算结果进行了分析,并指出了烟囱设计中应注意的问题.进一步阐明了计算高柔结构和特定条件下某些结构的竖向地震作用的必要性.

| Abstract: | Analysing the law of earthquake disaster of chimneys,it is taken into account that vertical earthquake force acts mainly in destruction of chimneys during an earthquake.A method of calculating vertical earthquake action by impulse way is proposed.By using the method,vertical earthquake action of a reinforced concrete chimney 190 meters high is calculated,and the result is analysed.Some problems worthy to be noted in design of chimney are discussed.The calculation of the vertical earthquake action in high rise construction design is necessary. |
