【Abstract】 Metal silo is a kind of ideal. apparatus for containment of materials in state of grain or powder. It has excellent and comprehensive technical characteristics of light weight, high strength, artistic figure, fireproof, proof against rats and birds, durability, shockproof, easy and rapid installation. Up to now, there is not a design code provided for engineers. Specially, the design of the vertical bar steel is weaker, which is the main member of the metal silo. Major accidents in the metal silo are caused by the vertical bar steel fallen. Therefore, some simple and effective methods for sol-ing problems have to be provided for engineers. The clastic foundation method is applied for solving strength and stability problems of the vertical bar steel. For strength calculating, the formulae of the internal force, caused by the sideway load, are derived from the semi-infinite beam method. For stability calculating, the approximate expression of the critical load-bearing capacity is derived from the energy method. These methods are available for engineering design.更多还原
