Aluminum I Beam | Single Span | Two Equal Spans | Three Equal Spans | Four Equal Spans

For a simply supported beam in a single span, the maximum displacement w_max

and the maximum normal stress stress_max

occur at the center of the beam.

The tabulated data listed in this page are calculated based on the area moment of inertia (I_xx = 25.5 in⁴) for the 6.00 × 4.692 Aluminum I Beam and the typical Young's modulus (E = 1.015 × 10⁷ psi) of aluminum alloys. Note that the typical yielding stress Yield

of aluminum alloys can range from 4061 to 7.614 × 10⁴ psi. The purpose of this page is to give a rough estimation of the load-bearing capacity of this particular beam, rather than a guideline for designing actual building structures. Please check your local building codes for regulatory requirements.

Note: The weight of the beam itself is not included in the calculation.
