Web Minimum Thickness = Depth of Section*sqrt(Yield Strength of Steel)/608
t_u = d*sqrt(f_y)/608
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Web Minimum Thickness - (Measured in Millimeter) - Web Minimum Thickness is the minimum thickness of a web in steel beams.
Depth of Section - (Measured in Millimeter) - Depth of Section is the depth of any section whether it can be a steel beam section or a steel column section.
Yield Strength of Steel - (Measured in Megapascal) - Yield strength of steel is the level of stress that corresponds to the yield point.

STEP 1: Convert Input(s) to Base Unit

Depth of Section: 350 Millimeter --> 350 Millimeter No Conversion Required
Yield Strength of Steel: 250 Megapascal --> 250 Megapascal No Conversion Required
