Factored Load on Member - (Measured in Newton) - Factored Load on Member is the specific factor designated by codes of practice to determine the strength of a structural member such as reinforced concrete.
Characteristic Compressive Strength - (Measured in Pascal) - The Characteristic Compressive Strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
Percentage of Compression Reinforcement - The percentage of compression reinforcement is the amount of structural reinforcement which is designed to carry compressive stresses of total gross area of concrete.
Characteristic Strength of Steel Reinforcement - (Measured in Pascal) - The Characteristic Strength of Steel Reinforcement is the yield strength of steel.
Gross Area of Concrete - (Measured in Square Meter) - Gross area of concrete is defined as total cross sectional area of column including reinforcement.
STEP 1: Convert Input(s) to Base Unit
Characteristic Compressive Strength: 20 Megapascal --> 20000000 Pascal (Check conversion ​here)
Percentage of Compression Reinforcement: 2 --> No Conversion Required
Characteristic Strength of Steel Reinforcement: 450 Megapascal --> 450000000 Pascal (Check conversion ​here)
Gross Area of Concrete: 1500 Square Millimeter --> 0.0015 Square Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pfm = (0.4*fck+(p/100)*(0.67*fy-0.4*fck))*Ag --> (0.4*20000000+(2/100)*(0.67*450000000-0.4*20000000))*0.0015
Evaluating ... ...
Pfm = 20805
STEP 3: Convert Result to Output's Unit
20805 Newton -->20.805 Kilonewton (Check conversion ​here)

## What is a Factored Load?

Whenever we are designing a RCC SLAB, we will be calculating the dead load and live load. Before finding out the ultimate bending moment, we shall find out the total of 1.5 DL+2.2 LL and this is called as factored loads and ultimate bending moment will be calculated.

## How to calculate the Factored Axial Load?

The factored concentric load applied on short, tied columns is resisted by
the concrete of area Ac and longitudinal steel of areas effectively held by lateral ties at intervals. Assuming the design strengths of concrete and steel are 0.4fck and 0.67fy we calculate the factored axial load.
