摘要
应用半解析有限单元法对烟囱(附有水塔)进行地震响应动力分析,所得到的烟囱的固有振动频率、固有振动振型及地震响应总设计内力是比较合理的,其计算结果可以作为有关设计人员的设计参考。
A dynamic analysis was made on the earthquake response of the 120m chimney with water tower in Baosteel by semi analysis finite element method.The computational results such as chimney’s natural vibration frequencies,natural vibration models and general designed internal force of earthquake response are reasonable,accurate and reliable,which will offer scientific references for chimney designers.
