Area of Prestressing Steel given Tension Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Prestressing Steel = Tension Force/(Prestressed Young's Modulus*Strain)
As = N_u/(E_p*ε)
This formula uses 4 Variables

Variables Used

Area of Prestressing Steel - (Measured in Square Meter) - Area of Prestressing Steel is the total cross sectional area of tendons.
Tension Force - (Measured in Newton) - Tension Force is a pulling force transmitted axially from the member.
Prestressed Young's Modulus - (Measured in Kilogram per Cubic Meter) - Prestressed Young's Modulus is in essence the stiffness of a material or how easily it is bended or stretched in prestressed members.
Strain - Strain is simply the measure of how much an object is stretched or deformed.

STEP 1: Convert Input(s) to Base Unit

Tension Force: 1000 Newton --> 1000 Newton No Conversion Required
Prestressed Young's Modulus: 38 Kilogram per Cubic Centimeter --> 38000000 Kilogram per Cubic Meter (Check conversion here)
Strain: 1.0001 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

As = N_u/(E_p*ε) --> 1000/(38000000*1.0001)

Evaluating ... ...

As = 2.63131581578684E-05

STEP 3: Convert Result to Output's Unit

2.63131581578684E-05 Square Meter -->26.3131581578684 Square Millimeter (Check conversion here)

FINAL ANSWER

26.3131581578684 ≈ 26.31316 Square Millimeter <-- Area of Prestressing Steel

Height of Crack Width at Soffit given Average Strain

LaTeX Go Height of Crack = (((Strain at Selected Level-Average Strain)*(3*Modulus of Elasticity of Steel Reinforcement*Area of Reinforcement*(Effective Depth of Reinforcement-Depth of Neutral Axis)))/(Crack Width*(Distance from Compression to Crack Width-Depth of Neutral Axis)))+Depth of Neutral Axis

Strain at Selected Level given Average Strain under Tension

LaTeX Go Strain at Selected Level = Average Strain+(Crack Width*(Height of Crack-Depth of Neutral Axis)*(Distance from Compression to Crack Width-Depth of Neutral Axis))/(3*Modulus of Elasticity of Steel Reinforcement*Area of Reinforcement*(Effective Length-Depth of Neutral Axis))

Average Strain under Tension

LaTeX Go Average Strain = Strain at Selected Level-(Crack Width*(Height of Crack-Depth of Neutral Axis)*(Distance from Compression to Crack Width-Depth of Neutral Axis))/(3*Modulus of Elasticity of Steel Reinforcement*Area of Reinforcement*(Effective Length-Depth of Neutral Axis))

Couple Force of Cross Section

LaTeX Go Couple Force = 0.5*Modulus of Elasticity of Concrete*Strain in Concrete*Depth of Neutral Axis*Crack Width

Area of Prestressing Steel = Tension Force/(Prestressed Young's Modulus*Strain)
As = N_u/(E_p*ε)

What does Young's Modulus mean?

Youngs modulus is a a measure of elasticity, equal to the ratio of the stress acting on a substance to the strain produced.
Young's modulus is a measure of the stiffness of an elastic material, and it is defined as the ratio of stress to strain. Rocks with low Young's modulus tend to be ductile and rocks with high Young's modulus tend to be brittle.

What are Prestressed Members?

In a prestressed concrete member, the internal stresses are introduced in a planned manner so that the stresses resulting from the superimposed loads are counteracted to the desired degree.
The principle behind prestressed concrete is that compressive stresses induced by high-strength steel tendons in a concrete member before loads are applied will balance the tensile stresses imposed in the member during service.
