Advantages and strength of steel structures

    Of course the larger the weight of the steel, but the strength was high more, compared with the weight of other structures, much less than the weight of the steel structure other structures. In the opposite load conditions, when the use of steel structures, steel structures lighter weight. When the opposite span and load, the proportion of reinforced concrete girder truss frame components rather 1/4 to 1/2, if using cold-formed steel beams are lighter. Because lighter weight, easy to carry and construction, and thus, the advantages of steel tricky to span large, high strength, bearing large structures, but also be practical to move, easy assembly and disassembly of the structure.
Steel has the advantage of strength:
    1, structural strength
    Steel texture, symmetry, all the elastic modulus, excellent ductility and toughness, elastic reality a plastic body, the more character competition conceptual basis for each intended to body. Thus, the precise intention of steel, higher strength, one of the main characteristics of the building is suitable for.
    2, high levels of industrial manufacturing
    Although the need to build the steel structure is relatively simple mechanical facilities and stringent process the request, but the maximum observed with the rest of the building structure, steel industrial manufacturing level, to a large number of manufacturing batches, to create high precision bowl, using people to build the field, site installation methods of construction, extended period, regress cost and economic progress.
    3, airtight better
    Because riveted structure can be done completely sealed, airtight and watertight some requests repression good container, heavy oil tanks, gas cylinders, pipes and other structures are suitable for steel plates and shells.
    4, heat resistance certainly exists
    When the house temperature within 250 ℃, small changes of the amount of steel, measuring 30 ℃ to obtain current, gradually increase the intensity, get 450-650 ℃, the intensity is zero. Thus, anti-tempered steel reinforced concrete is more heat-resistant than normal to measure not more than 250 ℃ occasions. At the request of the fire itself has special building, steel structure is necessary to use fire retardant paint, fire-resistant coating to the surface of the coating can block heat resistance.
