摘要
以往设计筒仓时，由于没有一套完整和实用的能考虑边缘效应的内力计算方法，大部分圆筒仓均按无矩理论计算薄膜内力，仅在配筋时对边缘附近壳体作构造加强。本文介绍了用有限元方法、采用电算手段分析贮煤圆筒仓内力的形成过程，并对有限元程序计算结果与《钢筋混凝土筒仓设计规范》方法计算结果进行了对比分析。本方法弥补了按无矩理论的近似性，避免了其他力学方法的繁锁计算。
Because of no complete and practical method for calculating the internal force with thinking of the edge effect, the film internal force of most silos is calculated according to the no moment theory and only the shell near the edge is reinforced. In this paper, the course of analysing the silo force by the method of finite element with computer is discribed. The result of finite element program is compared with 'Design Specification for Reinforced Concrete Silo'.The method of finite element makes up for the approximation of the no moment theory, avoids the complexity of other mechanics methods and provids a reference to the same kind engineering.
