STEP 0: Pre-Calculation Summary

Formula Used

End Zone Reinforcement = (2.5*Moment in Structures)/(Allowable Stress*Total Depth)
A_st = (2.5*M_t)/(σ_al*h)
This formula uses 4 Variables

Variables Used

End Zone Reinforcement - (Measured in Square Meter) - End Zone Reinforcement can be defined as the reinforcement which restrict the splitting of concrete, in addition to shear reinforcement, provided at each ends of member.
Moment in Structures - (Measured in Joule) - The Moment in Structures is an overturning effect (tends to bend or turn the member) created by the force(load) acting on a structural member.
Allowable Stress - (Measured in Newton per Square Meter) - The Allowable Stress is also known as working load and is the ratio of tensile strentgth and factor of safety.
Total Depth - (Measured in Centimeter) - Total Depth is described as the total depth of the member.

STEP 1: Convert Input(s) to Base Unit

Moment in Structures: 0.03 Newton Meter --> 0.03 Joule (Check conversion here)
Allowable Stress: 27 Newton per Square Meter --> 27 Newton per Square Meter No Conversion Required
Total Depth: 20.1 Centimeter --> 20.1 Centimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_st = (2.5*M_t)/(σ_al*h) --> (2.5*0.03)/(27*20.1)

Evaluating ... ...

What does Allowable Stress mean?

Allowable stress, or allowable strength, is the maximum stress that can be safely applied to a structure. The bearing stress is the force that pushes a structure divided by the area. We can define it as a contact pressure between two separate bodies. If we apply a compressive stress on a body, then there will be a reaction as internal stress in the material of the body. This internal stress is known as the bearing stress. The Allowable Bearing Stress in the Local Zone is the maximum stress that can be safely applied to a structure.

What is Transmission Length?

The transmission length, representing the distance from the free-end of the beam necessary to transmit the fully effective prestressing-force to the surrounding concrete, is a design parameter of paramount importance for PC members detailing.
The transmission length is influenced by many factors such as diameter of prestressing steel, initial or effective prestress, concrete strength, type of release, type of tendon, bond condition, concrete cover, surface condition and size of the section on the transmission length.
