Loss in Prestress given Creep Strain Solution

Follow our step by step solution on how to calculate Loss in Prestress given Creep Strain?

FIRST Step Consider the formula

Δf loss = E s \cdot ε cr,ult

Next Step Substitute values of Variables

∴

Δf loss = 200000MPa \cdot 0.8

Next Step Convert Units

∴

Δf loss = 200GPa \cdot 0.8

Next Step Prepare to Evaluate

∴

Δf loss = 200 \cdot 0.8

Next Step Evaluate

∴

Δf loss = 160000000000Pa

LAST Step Convert to Output's Unit

∴

Δf loss = 160GPa
