Steel structure safety technology
The steel structure is mainly made of steel and is one of the main types of building structures. The steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability. Therefore, it is especially suitable for building large-span and super-high and super-heavy buildings. The material is homogeneous and isotropic, and it is an ideal elastomer. It is in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, can withstand dynamic load well; construction period is short; its industrialization degree is high, and it can carry out specialized production with high degree of mechanization; High precision, high efficiency and good airtightness, so it can be used to build gas tanks, oil tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance. It is mainly used for load-bearing skeletons of heavy-duty workshops, plant structures subjected to dynamic loads, plate and shell structures, towering TV towers and mast structures, long-span structures such as bridges and warehouses, high-rise buildings and super high-rise buildings. In the future, steel structures should be studied for high-strength steels, which greatly increase the strength of the yield point. In addition, new types of steels, such as H-beams (also known as wide-flange steels) and T-shaped steels, and profiled steel plates, are required to accommodate large-span structures. And the need for super high-rise buildings. The steel structure is divided into light steel and heavy steel. Judging that there is no uniform standard, many experienced designers or project managers are often unable to fully explain, and can be considered and judged with some data. In addition, there is no thermal bridge light steel structure system. The steel structure itself is not energy-saving. This technology solves the problem of cold and hot bridges of buildings with clever special joints; the small truss structure allows cables and water pipes to pass through the wall. The construction and decoration are convenient; the energy saving is a building system of a 7-story residential building with cold-formed thin-walled steel.
