摘　　要：以直径为22 m,高为24 m的焊接钢板筒仓为研究对象,应用有限元分析软件SAP2000与Midas Gen对不同加劲肋间距的钢板筒仓进行单工况静力分析,探讨了不同的竖向加劲肋间距对钢板最大环向应力的影响,为工程设计与科学研究提供参考依据。Taking the welded steel silo with a diameter of 22 m and a height of 24 m as the object of study, and make a static analysis on one load condition for the steel silo with different stiffening rib space by finite element software SAP2000 and Midas Gen, discussed the effect on the maxi- mal circumferential stress with different space of stiffening rib. So the reliable mechanical basis for engineering design and scientific study of the welded steel silo are offered.
