大型钢筋混凝土筒仓圆锥壳仓底力学模型的分析与应用

Analysis and Application of Mechanical Model for Cone Bottom of the Huge RC Silo

大型钢筋混凝土筒仓仓底往往要承受很大的荷载,因而合理的对仓底进行受力分析具有很强的现实意义。采用薄壳理论对大型钢筋混凝土筒仓圆锥壳仓底内力的计算公式进行了推导,和相关规范公式算法进行了比较,并进一步通过对实例的有限元分析验证了其合理性,同时细致的分析了其受力行为。

The bottom of the huge RC silo is always suffered by great amount of loads,so it' s significant in reality to make the reasonable analysis of silo bottom.The formulas to understand the internal force in huge RC silo bottom are deduced,comparison with related specifications is drawn,and its rationality is testified by finite element method,cone bottom' s mechanic behavior is carefully studied.
