## Characteristic Compressive Strength of Concrete given Factored Axial Load in Spiral Columns Solution

STEP 0: Pre-Calculation Summary
Formula Used
Characteristic Compressive Strength = ((Factored Load/1.05)-0.67*Characteristic Strength of Steel Reinforcement*Area of Steel Reinforcement)/(0.4*Area of Concrete)
fck = ((Pf/1.05)-0.67*fy*Ast)/(0.4*Ac)
This formula uses 5 Variables
Variables Used
Characteristic Compressive Strength - (Measured in Megapascal) - 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.
Factored Load - (Measured in Kilonewton) - The factored load is multiplied by a specific factor designated by codes of practice to determine the strength of a structural member such as reinforced concrete.
Characteristic Strength of Steel Reinforcement - (Measured in Megapascal) - The Characteristic Strength of Steel Reinforcement is the yield strength of steel.
Area of Steel Reinforcement - (Measured in Square Millimeter) - The area of steel reinforcement for columns or beams is defined as an area of vertical reinforcement which is provided to absorb the bending tensile stresses in the longitudinal direction.
Area of Concrete - (Measured in Square Millimeter) - The Area of Concrete is defined as the concrete area in a beam or column excluding the area of reinforcement.
STEP 1: Convert Input(s) to Base Unit

## What is the Compressive Strength of Concrete?

Strength of hardened concrete is measured by the compression test. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it. The compressive strength of concrete is measured by crushing cylindrical concrete specimens in a compression testing machine.

## What is a Factored Load & Spiral Columns?

Whenever we are designing an 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 the ultimate bending moment will be calculated.
When the transverse reinforcement is used in the form of helical hoops then it is known as a spirally reinforced column. The longitudinal reinforcement bars are arranged in the spiral column by a closely spaced continuous spiral. The spiral columns are usually circular in shape.
