Safety of steel structure buildings

Steel structure is mainly composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of profiled steel and steel plates. Welds, bolts or rivets are usually used to connect the components or components. Because of its light weight and simple construction, it is widely used in large-scale factory buildings, venues, super high-rise and other fields.

Steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability, so it is particularly suitable for building large-span, super-high and super-heavy buildings; good homogeneity and isotropy of materials, which belongs to ideal elastomer, and most in line with the basic assumptions of general engineering mechanics; good plasticity and toughness of materials, which can cause large deformation. It can withstand dynamic loads well, the construction period is short, the industrialization degree is high, and the specialized production with high mechanization degree can be carried out. High strength steel should be studied in steel structure to improve its yield point strength greatly. In addition, new types of section steel, such as H-section steel (also known as wide flange section steel) and T-section steel, as well as profiled steel sheet, should be rolled to meet the needs of large-span structures and super high-rise buildings.

Moreover, the stability and safety of steel structure are higher. Qingdao Lida light steel structure building can withstand earthquake of magnitude 9, which is due to the traditional brick-concrete and steel-concrete buildings.
