What Is an I Beam
I beam is a shape of structural steel used in buildings and it is also known as H, W, wide, universal beam, or rolled joist. They are designed to play a key role as a support member in structures. These beams have the capacity to withstand various types of loads.
Its name was given so because of the resemblance of its cross-section to the letter I. These beams are frequently utilized to form beams and columns in a variety of dimensions and specs. It is crucial for civil engineers and foremen to understand the importance of I beams in steel structures.
Whether the I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is large, so it can only be directly used in the web plane bending members or it is composed of lattice stress members. The axial compression member or the member that is perpendicular to the web plane and bent should not be used, which makes it have great limitations in the application range. I-beams are widely used in buildings and other metal structures.
Ordinary I-steel, light I-steel, due to the relatively high and narrow section size, the moment of inertia of the two main axes of the section is relatively different, which makes it have great limitations in the application range. The use of I-beams should be selected according to the requirements of the design drawings.
The selection of I-steel in structural design should be based on its mechanical properties, chemical properties, weldability, structural size and other reasonable selection of I-steel for use.
