T_u = 0.85*5*sqrt(f'_c)*Σx²y
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

Ultimate Design Torsional Moment - (Measured in Newton Meter) - Ultimate Design Torsional Moment,Torsion is the twisting of a beam under the action of a torque (twisting moment).
Specified 28-Day Compressive Strength of Concrete - (Measured in Newton per Square Millimeter) - Specified 28-Day Compressive Strength of Concrete is the maximum compressive load concrete can withstand after the concrete mix is formed.
Sum for Component Rectangles of Section - Sum for Component Rectangles of Section of the product of square of the shorter side and the longer side of each rectangle.

STEP 1: Convert Input(s) to Base Unit

Specified 28-Day Compressive Strength of Concrete: 50 Megapascal --> 50 Newton per Square Millimeter (Check conversion here)
Sum for Component Rectangles of Section: 20.1 --> No Conversion Required
