摘要
本文用有限元模型分析了钢筋混凝土浅圆仓仓顶的弹性稳定性,计算了其屈曲临界荷载。并通过极限分析理论,给出了浅圆仓仓顶极限荷载的计算方法。工程实例计算表明,钢筋混凝土浅圆仓仓顶通常是弹性稳定的,应当使用极限分析方法确定其设计使用荷载。
The elastic stability of reinforced concrete silo shell roof is analyzed by using finite-element model. The elastic critical buckling loads of the shell roof are calculated. Based on the limit analysis theory, the method for calculating the ultimate load of silo shell roof is also presented. The analyses of practical applications indicate that the reinforced concrete silo shell roof in common practical use is always elastic stable, and the limit analysis theory should be used to assess the design proposal.
