Brief introduction of I-beam:
I-beam, also known as steel Beam (English name I Beam), is a strip of steel with an I-shaped section. I-beam is divided into ordinary and light I-beam, H – shaped steel three. I-beam is widely used in various building structures, atlas Bridges, vehicles, supports, machinery and so on. Ordinary I-beam and light I-beam wing root gradually thin to the edge, there is a certain Angle, ordinary I-beam and light I-beam type is represented by the number of centimeters of the waist height Arabic number, web, flange thickness and flange width of different specifications in the waist height (h)× leg width (b)× waist thickness (d). The specification of ordinary I-beam can also be expressed by the model, the model indicates the number of centimeters of waist height, such as the general 16#. If there are several different leg widths and waist thicknesses for I-beams with the same waist height, A, B, and C should be added to the right side of the model to distinguish them.
Use of I-beam:
Ordinary I-beam, light I-beam, because the section size is relatively high, narrow, so the moment of inertia of the two main sleeves of the section is relatively large, therefore, generally can only be directly used in the web plane bending members or the composition of the lattice structure of the force members. It is not suitable to use axial compression members or bending members perpendicular to the web plane, which makes it very limited in the scope of application.
