    Perpendicular frictional forces between silage and steel silo were measured using silages and a model of a steel silo. Silages used in the experiments were made of true grasses and dent corn. The percentages of water content of the silages were adjusted to 70, 55 and 40 %.
    Characteristics of the frictional forces of each silages became clear. The magnitude of the frictional forces of grass silages were apparently different from those of the dent corn silages. Total frictional force acting on the actual silo was estimated based on the experimantal results and compared with the value obtained from the current design standard. It has been clarified that when dent corn silage is prepared in the silo, the frictional force estimated from the design standard is rather over-estimated compared with the experimental result.
