[提要] 螺旋咬邊式鋼板倉在我國屬于新型結(jié)構(gòu)，其受力狀況復(fù)雜。用有限元法對螺旋咬邊式鋼板倉結(jié)構(gòu)進(jìn)行了有限元分析。計算結(jié)果表明鋼板倉在相對高度ht / hn = 0.03～0.2范圍內(nèi)應(yīng)力和變形較大，這一部位應(yīng)是鋼板倉的重點防護(hù)部位，應(yīng)加強板和梁的強度和剛度。計算結(jié)果對工程設(shè)計和應(yīng)用有參考意義。
[關(guān)鍵詞] 鋼板倉 有限元法 應(yīng)力 變形 螺旋咬邊The stresses and deformations of the steel silo are computed with the finite element method under wind load and the full load. The computed results show the stresses and deformations of the steel silo are higher in the relative height ht / hn = 0.03～0.2,in which the rigidity and strength should be strengthened for steel silo generally. The results are very helpful for the design and application of steel silo.
Keywords: steel silo; finite element method; stress; deformation; screwed holding
