Steel Box Section Strength Calculator

The deflection and bending stress of a steel hollow beam of length 20 inches width 30 inches height 30 inches having a wall thickness of 10 inches and beam weight of 200 pounds can be calculated as follows.

If gross and effective section property values are required please contact allied tube conduit s mechanical tube pipe division. 271188 mm 4 perpendicular distance from the neutral axis.

Below is the raw unrounded data. Beam deflection calculators solid rectangular beams hollow rectangular beams solid round beams. The calculated section property values do not comply with the aisi or aisc specifications since minimum material thickness and rounded corners were not used.

76x38x1 6 rhs force of load. If bending stress exceeds the materials yield strength it will be permanently deformed and not return to its original shape. This calculator may give you a rough idea of the deflection of metal tubing but it s not accurate enough to do any more than estimate it.

0 05 n mm beam deflection from beams own weight. Calculator for hollow structural sections square calculators. If the deflection is large enough to permanently bend the tube then all bets are off.

210000 n mm 2 moment of inertia. Inside width width 2 wall thickness 30 2 10 10. 700 n continuous load force per mm.

Calculate the deflection of hollow rectangle and its bending stress. Yield strength of steel moment of turning force half the material thickness second moment of inertia we don t know the amount or moment of turning force required to meet that of the yield strength bend and not return of the steel as this is what we are trying to find out. The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing.
