Area of Prestressing Tendon for Known Tensile Strength of Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Prestressing Steel = Tensile Force/(0.87*Tensile Strength of Prestressed Steel)
As = P_uR/(0.87*F_pkf)
This formula uses 3 Variables

Variables Used

Area of Prestressing Steel - (Measured in Square Meter) - Area of Prestressing Steel is the total cross sectional area of tendons.
Tensile Force - (Measured in Newton) - Tensile Force is the stretching force acted on the section having prestressed tendons within it.
Tensile Strength of Prestressed Steel - (Measured in Pascal) - Tensile Strength of Prestressed Steel is the tensile capacity of the prestressed tendons.

STEP 1: Convert Input(s) to Base Unit

Tensile Force: 4.35 Kilonewton --> 4350 Newton (Check conversion here)
Tensile Strength of Prestressed Steel: 249 Megapascal --> 249000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

As = P_uR/(0.87*F_pkf) --> 4350/(0.87*249000000)

Evaluating ... ...

As = 2.00803212851406E-05

STEP 3: Convert Result to Output's Unit

2.00803212851406E-05 Square Meter -->20.0803212851406 Square Millimeter (Check conversion here)

FINAL ANSWER

20.0803212851406 ≈ 20.08032 Square Millimeter <-- Area of Prestressing Steel

What are the characteristic features of Prestressing Steel?

For prestressed concrete, high strength steel is used to provide high elongation to maintain the steel stress after the prestress loss.
Ideally, it should also:
• Remain elastic up to relatively high stress.
• Show sufficient ductility before failure.
• Have good bonding properties, low relaxation, good resistance to corrosion.
• Be economical and easy to handle
