Rectangular Steel Tubing Deflection Formula

The formula to calculate deflection, shear, maximum moment and resultant are provided in the rectangular steel tubing deflection formula. The rectangular steel tubing is durable, easy to paint, fabricate and used in many industrial applications like bridge construction. The deflection and slope is zero at the support. The deflection formula is to multiply the constant value 0.0092 with length of support and weight of beam and divided by the inertia and Young's modulus.

Formula:

R1 = (7 × w × L) / 16
R2 = (5 × w × L) / 8
R3 = (-w × L) / 16
V2 = (9 × w × L) / 16
Mmax = (49 × w × L2) / 512
M1 = (w × L2) / 16
My = (w × y) × ((7 × l) - (8 × y)) / 16
Δmax = 0.0092 × (w × L4) / (E × I)


Where,

w = Load on Beam
L = Between Supports
y = Point of Interest
E = Youngs Modulus
I = Moment of Inertia
R1 = Resultant 1
R2 = Resultant 2
R3 = Resultant 3
V2 = Shear at R2
Mmax = Max Moment
M1 = Moment at R2
My = Moment at y
Δmax = Deflection
