Area of Prestressing Steel given Transformed Area Solution

STEP 0: Pre-Calculation Summary
Formula Used
Area of Prestressing Steel = (Transformed Area of Prestressed Member-Transformed Area of Concrete)/Modular Ratio
As = (At-AT)/m
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.
Transformed Area of Prestressed Member - (Measured in Square Meter) - The Transformed Area of Prestressed Member is the area of the member when steel is substituted by an equivalent area of concrete.
Transformed Area of Concrete - (Measured in Square Meter) - Transformed Area of Concrete is the modified or altered surface of a concrete structure resulting from changes or treatments.
Modular Ratio - The modular ratio is the ratio of the elastic modulus of a particular material in a cross-section to the elastic modulus of the “base” or the reference material.
STEP 1: Convert Input(s) to Base Unit
Transformed Area of Prestressed Member: 4500.14 Square Millimeter --> 0.00450014 Square Meter (Check conversion here)
Transformed Area of Concrete: 1000 Square Millimeter --> 0.001 Square Meter (Check conversion here)
Modular Ratio: 175 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
As = (At-AT)/m --> (0.00450014-0.001)/175
Evaluating ... ...
As = 2.00008E-05
STEP 3: Convert Result to Output's Unit
2.00008E-05 Square Meter -->20.0008 Square Millimeter (Check conversion here)
FINAL ANSWER
20.0008 Square Millimeter <-- Area of Prestressing Steel

Area of Prestressing Steel given Transformed Area Formula

Area of Prestressing Steel = (Transformed Area of Prestressed Member-Transformed Area of Concrete)/Modular Ratio
As = (At-AT)/m

What is Loss of Prestress & What are the Losses in Prestressing Concrete?

A reduction in initial pre-stress resulting from the combined effect of creep, shrinkage or elastic shortening of the concrete, relaxation of the reinforcing steel, frictional losses resulting from the curvature of the draped tendons and slippage at the anchorage.
In a prestressed concrete beam, the loss is due to the following:
1. Elastic shortening
2. Shrinkage of concrete
3. Creep of concrete
4. Frictional loss
5. Relaxation of steel
6. Anchorage take-up

What are the Classification of Prestressing Losses?

The losses are broadly classified into two groups, immediate and time-dependent.
The losses due to elastic shortening of the member, friction at the tendon-concrete interface and slip of the anchorage are the immediate losses.
The time-dependent losses occur during the service life of the prestressed member. The losses due to the shrinkage and creep of the concrete and the relaxation of the steel are time-dependent losses.
