Stress in Concrete given Prestress Drop Solution

STEP 0: Pre-Calculation Summary
Formula Used
Stress in Concrete Section = Prestress Drop/Modular Ratio for Elastic Shortening
fconcrete = Δfp/mElastic
This formula uses 3 Variables
Variables Used
Stress in Concrete Section - (Measured in Megapascal) - Stress in Concrete Section is the force per unit area of the concrete section considered.
Prestress Drop - (Measured in Megapascal) - Prestress Drop is the drop in applied prestress force due to strain in tendons.
Modular Ratio for Elastic Shortening - Modular Ratio for Elastic Shortening 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
Prestress Drop: 10 Megapascal --> 10 Megapascal No Conversion Required
Modular Ratio for Elastic Shortening: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
fconcrete = Δfp/mElastic --> 10/0.6
Evaluating ... ...
fconcrete = 16.6666666666667
STEP 3: Convert Result to Output's Unit
16666666.6666667 Pascal -->16.6666666666667 Megapascal (Check conversion ​here)
FINAL ANSWER
16.6666666666667 16.66667 Megapascal <-- Stress in Concrete Section

What are Prestress Losses?

The prestress losses are defined as the loss of tensile stress in the prestress steel which acts on the concrete component of the prestressed concrete section. In pre-tensioned concrete, the four major sources of prestress losses are elastic shortening (ES), creep (CR), shrinkage (SH) and relaxation (RE). Additionally, prestress losses are further affected by variations in material properties of the concrete.
