Commonly termed an “I” beam because of its shape, beams provide great load bearing support when used horizontally or standing as columns. I-beams are the choice shape for structural steel builds because the I-beam makes it uniquely capable of handling a variety of loads. The shape of I-beams makes them excellent for unidirectional bending parallel to the web. The horizontal flanges resist the bending movement, while the web resists the shear stress.
Understanding the I-beam is a basic necessity for the modern civil engineer or construction worker. Engineers use I-beams widely in construction, forming columns and beams of many different lengths, sizes, and specifications.
An I-beam is made by rolling or milling steel which means the I-beam is often limited by the capacity or size of the milling equipment.
I-beams come in a variety of weights, section depths, flange widths, web thicknesses, and other specifications for different purposes. When ordering I-beams, buyers classify them by their material and dimensions. For example, an 11×20 I-beam would have an 11-inch depth and a weight of 20 pounds per foot. Builders choose specific sizes of I-beams according to the needs of the particular building. A builder has to take many factors into account, such as:
The builder chooses an I-beam with a web thickness that won’t fail, buckle, or ripple under tension.
The flanges are chosen to prevent buckling locally, sideways, or torsionally.
The builder will choose a thickness to minimize the deformation of the beam.
A certain mass and stiffness are selected to prevent vibrations in the building.
The strength of the I-beam’s cross-section should accommodate yield stress.
