Characteristic Strength of Compression Reinforcement given Factored Load in Spiral Columns
​ Go Characteristic Strength of Steel Reinforcement = ((Factored Load/1.05)-(0.4*Characteristic Compressive Strength*Area of Concrete))/(0.67*Area of Steel Reinforcement)
Characteristic Compressive Strength of Concrete given Factored Axial Load in Spiral Columns
​ Go Characteristic Compressive Strength = ((Factored Load/1.05)-0.67*Characteristic Strength of Steel Reinforcement*Area of Steel Reinforcement)/(0.4*Area of Concrete)
Area of Concrete given Factored Axial Load
​ Go Area of Concrete = ((Factored Load/1.05)-0.67*Characteristic Strength of Steel Reinforcement*Area of Steel Reinforcement)/(0.4*Characteristic Compressive Strength)
Factored Axial Load on Member of Spiral Columns
​ Go Factored Load = 1.05*(0.4*Characteristic Compressive Strength*Area of Concrete+0.67*Characteristic Strength of Steel Reinforcement*Area of Steel Reinforcement)

## Volume of Helical Reinforcement in One Loop Formula

Volume of Helical Reinforcement = pi*(Diameter of Core-Diameter of Spiral Reinforcement)*Area of Steel Reinforcement
Vh = pi*(dc-Φ)*Ast

## What is a Helical Reinforcement?

Helical reinforcement is capable of protecting columns or piles against seismic loads. Whenever the column reaches the failure condition, then concrete outside hoops will crack & it falls off first, followed by the whole columns’ eventual failure.

## How to Calculate Volume of Helical Reinforcement in One Loop?

Volume of Helical Reinforcement in One Loop calculator uses Volume of Helical Reinforcement = pi*(Diameter of Core-Diameter of Spiral Reinforcement)*Area of Steel Reinforcement to calculate the Volume of Helical Reinforcement, The Volume of Helical Reinforcement in One Loop formula is defined as the volume of the given helical reinforcement which is small-diameter reinforcement wrapped around the main or longitudinal reinforcement, restraining the lateral expansion of the concrete under compression, and thus strengthening the structure. Volume of Helical Reinforcement is denoted by Vh symbol.

How to calculate Volume of Helical Reinforcement in One Loop using this online calculator?
