Abstract：The formulas for the radial displacement and inner forces of large-diameter PCCS (prestressed concrete coal silo) were derived ,based on the mechanics of cylindrical shell and considering the boundary condition at the bottom. The prestressed action was equivalent as the internal pressure. The two reaults calculated by the formulas and the FEA have good agreement. The results show that the results within 2.5(√Rt) from the bottom may be remarkably different be-tween the formula and the traditional design theory, which indicates that the precise design is necessary for this region.
