Web Thickness for Minimum Moment of Inertia of Transverse Stiffener Solution

STEP 0: Pre-Calculation Summary

Formula Used

Web Thickness = (Moment of Inertia/(Actual Stiffener Spacing*((2.5*Clear Distance between Flanges^2/Actual Stiffener Spacing^2)-2)))^(1/3)
t = (I/(a_o*((2.5*D^2/a_o^2)-2)))^(1/3)
This formula uses 4 Variables

Variables Used

Web Thickness - (Measured in Meter) - Web Thickness is the thickness of the web of the I-section of any beam or column which is between the flanges.
Moment of Inertia - (Measured in Meter⁴) - The moment of inertia is the quantity expressed by the body resisting angular acceleration, which is the sum of the product of the mass with its square of the distance from the axis of rotation.
Actual Stiffener Spacing - (Measured in Meter) - The actual stiffener spacing is the distance between two stiffeners which is placed either longitudinal (aligned in the span) or transverse (normal to the span).
Clear Distance between Flanges - (Measured in Meter) - The clear distance between flanges is the support length of the web of an I-section.

STEP 1: Convert Input(s) to Base Unit

Moment of Inertia: 12320 Millimeter⁴ --> 1.232E-08 Meter⁴ (Check conversion here)
Actual Stiffener Spacing: 50 Millimeter --> 0.05 Meter (Check conversion here)
Clear Distance between Flanges: 45 Millimeter --> 0.045 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = (I/(a_o*((2.5*D^2/a_o^2)-2)))^(1/3) --> (1.232E-08/(0.05*((2.5*0.045^2/0.05^2)-2)))^(1/3)

Evaluating ... ...

t = 0.0214404336438616

STEP 3: Convert Result to Output's Unit

0.0214404336438616 Meter -->21.4404336438616 Millimeter (Check conversion here)

FINAL ANSWER

21.4404336438616 ≈ 21.44043 Millimeter <-- Web Thickness

What is Web thickness?

The thickness of the vertical center section of a steel beam (“D”).The part of the Structural Beam that provides resistance to shear forces (breaking, tearing apart, or collapsing) is the web, while the flanges resist the bending movement of the section

What is Moment of inertia?

The second moment of area, also known as area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. If the piece is thin, however, the mass moment of inertia equals the area density times the area moment of inertia
