I-beam itself has different classifications according to structural differences. Ordinary I-beams are mainly used as load-bearing beam members for buildings, while special H-shaped I-beams are more widely used, such as HW-type I-beams. Strong pressure.
Therefore, it is often used as a load-bearing column and a structural column in steel structures. Due to its strong tensile strength, HM-type I-beams are often used as frame beams in large platforms and large provocative buildings.
I-shaped steels, whether of ordinary type or light type, have relatively large and narrow cross-sectional dimensions, so the difference of the moments of inertia of the two main axes of the section is large, so it can only be used directly in the plane of the web. A member or a group of structurally stressed members. It is not suitable for the axial compression member or the member that is curved perpendicular to the plane of the web, which makes it have a large limitation in the application range. I-beams are widely used in construction or other metal structures.
Ordinary I-steel, light I-beam, because the cross-sectional dimensions are relatively high and narrow, so the difference of the moment of inertia of the two main sleeves of the section is large, which makes it have great limitations in the application range. The use of I-beams should be selected in accordance with the requirements of the design drawings.
In the structural design, the I-beam should be selected according to its mechanical properties, chemical properties, weldability and structural dimensions.
