Every building is composed of various components, and the main function of each component is also very different.Steel members are now the main component of many building structures, and the steel members used in various parts have different performance.The construction of steel structure engineering is composed of five parts: steel column, steel beam, steel roof truss, steel roof and wall, as well as other parts and steel components.What kind of influence does the common main components of steel structure engineering have on the overall structure quality? 

Illustration of components of steel structure engineering

In the steel structure engineering structure, the most common main components include steel column and steel beam, which are a large part of support and load-bearing, and as an important part of the structure.The section forms of steel column are divided into solid web column and lattice column.Solid web column has a whole section, the most commonly used is I-section, H-section; the cross-section of lattice column is divided into two or more limbs, each limb is connected with batten or batten plate, when the load is large and the column body is wide, the steel consumption is relatively low.

 Steel beam steel beam has steel beam, composite beam.Steel beams can be used for crane beam and working platform beam in workshop, floor beam in multi-storey building and purlin in roof structure.The section steel beam is made of hot-rolled I-beam or channel steel, which is simple to process and low in cost, but its section size is limited by certain specifications.When the load and span are large and the steel section can not meet the requirements of strength, stiffness or stability, composite beams are used. 

Composite beam of steel structure engineering

The composite beam is welded or riveted by steel plate or section steel.As riveting costs labor and materials, welding is often the main method.The commonly used welded composite beams are H-shaped section and box section composed of upper and lower flange plates and webs. The latter is more expensive, and the manufacturing process is more complicated, but it has larger bending stiffness and torsional stiffness, which is suitable for cases with high lateral load and torsion requirements or limited beam height.

 The main components of steel structure engineering can be formed by selecting different materials. Different materials have different natural properties and quality. Different types of plants can also be built, such as multi-storey steel structure engineering, light steel structure engineering, brick concrete structure workshop and other types of buildings. Only by controlling the quality of relevant components can the installation quality of the overall structure be improved。
