本文除考虑烟囱钢内筒自重、风、和水平地震力强度计算之外，增加了钢内筒的烟气压力、烟气温度、竖向地震力的应力计算公式，最后按第４强度理论来控制强度设计。还就局部扭矩和筒身振动等方面进行分析研究。可供工程设计和烟囱规范修订参考。最后还提出了悬挂式钢内筒的结构设计初步思路和原则，供读者讨论研究，以期尽早设计、施工我国自己的悬挂式钢烟囱。
In this paper, in addition to the calculation of the self-weight, wind, and horizontal seismic force strength of the chimney steel inner cylinder, the calculation formulas for the pressure of the flue gas, the flue gas temperature, and the vertical seismic force of the steel inner cylinder are added. Finally, the fourth strength theory is used. Control strength design. It also analyzes and studies the local torque and shaft vibration. Available for engineering design and chimney specification revision reference. Finally, the preliminary design ideas and principles for the structural design of the suspended steel inner tube were also proposed for readers to discuss and study, in order to design and construct our own hanging steel chimney as early as possible.
