Glossary » Beams » Simply Supported » Uniformly Distributed Load » Two Equal Spans » Aluminum I Beam » 4.00 × 2.793
For a simply supported beam in two equal spans, we compute the displacement at the middle of each span
and the maximum normal stress
occuring at the center support of the beam.
The tabulated data listed in this page are calculated based on the area moment of inertia (Ixx
= 6.71 in4
) for the 4.00 × 2.793 Aluminum I Beam
and the typical Young's modulus (E
= 1.015 × 107
psi) of aluminum alloys. Note that the typical yielding stress
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.
