某垃圾电站钢筋混凝土方形烟囱有限元分析

Finite element analysis of reinforced concrete square chimneyin a garbage power station

依托某垃圾电站工程中钢筋混凝土方形烟囱实例,采用有限元分析软件midas Gen建立烟囱有限元模型,研究了钢筋混凝土方形烟囱考虑顺风向风振影响的风荷载作用下的应力分布,进行了小震作用下的时程分析,探讨方形烟囱设计关键部位。研究成果可用于指导方形烟囱工程设计。

Based on an example of reinforced concrete square chimney in a garbage power station project,this research studies the stress distribution of the reinforced concrete square chimney under wind load.The influence of wind vibration along the wind direction and the time history analysis results under frequent earthquakes are studied by using the finite element analysis software midas Gen.The research results can be used to guide the design of square chimney in projects.
