摘要
以实际工程装配式钢板筒仓BC2425为研究对象,分别根据《粮食钢板筒仓设计规范》(GB 50322-2001)和通用有限元软件ANSYSTM对开洞满仓工况下的钢板筒仓进行了应力分析.结果表明:仓体的较大应力不仅出现在仓体底部,还出现在仓壁开口处、仓壁与加劲肋的截面改变处.仓壁开口处和仓壁与加劲肋的截面改变处可能成为筒仓的薄弱部位.针对上述薄弱部位,通过数值分析确定了具体的增强方案.
"Code for design of grain steel silos"(GB 50322-2001)and ANSYSTM were utilized to analysis stress for an assemblage steel silo with a large bin gate.The conclusion was determined that in addition to the bottom of silo,larger stress was appeared around the opening in silo wall and the changed cross-section of silo wall and rib stiffener.Therefore the opening in silo wall and the changed cross-section of silo wall and rib stiffener could be the vulnerable points in the silo.According to the vulnerable points listed above,the specific strengthening program is determined.
