Application characteristics of I-beam
Due to the relatively high and narrow cross-sectional dimensions of ordinary I-beams and light-weight I-beams, the moment of inertia of the two main sleeves of the cross-section is quite different, which greatly limits their application range. The use of I-beams should be selected according to the requirements of the design drawings.
Whether I-shaped steel is ordinary or light, due to the relatively high and narrow cross-sectional dimensions, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for bending in the plane of its web. components or form them into lattice-type stressed components. It is not suitable to use axial compression members or members that are perpendicular to the web plane and are curved, which greatly limits its application range. I-beams are widely used in buildings or other metal structures.

When selecting I-beams in structural design, reasonable I-beams should be selected based on their mechanical properties, chemical properties, weldability, structural dimensions, etc.
