Loss in Prestress given Creep Strain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Loss in Prestress = Modulus of Elasticity of Steel Reinforcement*Ultimate Creep Strain
Δf_loss = E_s*ε_cr,ult
This formula uses 3 Variables

Variables Used

Loss in Prestress - (Measured in Gigapascal) - Loss in Prestress is the loss found in the prestress due to shrinkage or creep or anchorage slip etc.
Modulus of Elasticity of Steel Reinforcement - (Measured in Gigapascal) - Modulus of Elasticity of Steel Reinforcement is a measure of its stiffness.
Ultimate Creep Strain - Ultimate Creep Strain is caused due to the sustained load for a long period of time.

STEP 1: Convert Input(s) to Base Unit

Modulus of Elasticity of Steel Reinforcement: 200000 Megapascal --> 200 Gigapascal (Check conversion here)
Ultimate Creep Strain: 0.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δf_loss = E_s*ε_cr,ult --> 200*0.8

Evaluating ... ...

Δf_loss = 160

When Circular Prestressing is is done?

Liquid retaining structures, such as circular pipes, tanks and pressure vessels are having hoop tension developed due to the initial fluid pressure. A reinforced concrete pressure pipe requires a large amount of reinforcement to ensure low tensile stresses. But the circumferential hoop compression induced in concrete by prestressing counter balances, the hoop tension developed. In addition, circular prestressing safe guard against shrinkage cracks is liquid retaining structures provide economical use of the materials.
