Definition of Steel Structure

Steel structure is a structure composed of steel materials and 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 steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. Welding seams, bolts, or rivets are usually used to connect various components or parts. Due to its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rusting, and generally require rust removal, galvanizing, or coating, as well as regular maintenance. During use, the steel must have good mechanical and processing properties, and materials such as Q235 in carbon steel and 16Mn in low-alloy steel meet the requirements. The durability of steel is affected by factors such as corrosion and high temperature, and protective measures include galvanizing, anodizing, and other methods.

The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation, making it particularly suitable for constructing large-span, ultra high, and ultra heavy buildings; The material has good homogeneity and isotropy, and belongs to the ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization.
