Estimate I-beam area, weight, moment of inertia, section modulus, load, support reactions, bending moment, bending stress, shear, deflection, and basic utilization checks. Use this I-beam calculator for steel I-beams, wide flange beams, built-up I sections, and preliminary structural planning.
Geometry:
The calculator estimates I-beam area, web height, moment of inertia, section modulus, and beam weight from the dimensions entered.
Load:
The calculator combines applied load, estimated beam self weight, and center point load to estimate total beam load.
Bending:
The calculator estimates maximum bending moment and divides it by section modulus to estimate bending stress.
Deflection:
The calculator estimates simple-span deflection and compares it to the selected limit, such as L/360 or L/480.
An I-beam calculator helps estimate the weight, stiffness, bending demand, and deflection of a beam before comparing sizes or reviewing a preliminary layout.
It can help compare beam geometry, section properties, self weight, reactions, shear, moment, bending stress, deflection, and basic utilization percentages.
Your result shows estimated I-beam area, weight per foot, total beam weight, moment of inertia, section modulus, total load, reactions, maximum shear, maximum bending moment, bending stress, deflection, allowable deflection, and utilization percentages. These are simplified planning estimates only.
An I-beam is a structural beam with top and bottom flanges connected by a vertical web. The shape helps resist bending efficiently.
An I-beam is one type of steel beam. Steel beams can also include wide flange beams, channels, HSS members, and other structural shapes.
Use official steel table values for final design. This calculator estimates simple I-shaped section properties from entered dimensions for preliminary planning.
No. Final I-beam design may require official section properties, shear checks, lateral-torsional buckling checks, bearing checks, bracing, connections, code load combinations, and professional review.
