The advantages and disadvantages of steel structurePosted by:W&G International Co., Ltd.
Steel structure refers to the structure made of steel and steel plate as the structure, compared with other materials, steel structure has the characteristics as follows:
(I) steel structure of light weight, high strength. Constructed of steel structure residence weight is reinforced concrete residential around 1/2, but, compared with other materials, much, high strength of steel so that, under the same loading condition, the steel structure than the reinforced concrete structure of light. (2) the steel has good plasticity and toughness.. Good plasticity refers to the steel under static load, when the stress exceeds the yield point, can produce significant residual deformation (plastic deformation) and the nature is not immediately fracture. The steel has good toughness, refers to the property of not easily brittle fracture under dynamic loads. (3) the steel material is uniform, isotropic body closer to the homogeneous. Steel internal organization very close to homogeneous, and the all directions of the physical force degree can basically the same, relatively close to the preparation of isotropic body. Assuming that these properties and mechanical calculation of steel in very good agreement with the actual steel structure, so the stress status and engineering mechanics calculation results most consistent with the.
