eng.prestressed-concrete-loss-elastic Calculator
Calculates elastic shortening loss in prestressed concrete from applied prestress force and concrete modulus. Elastic shortening loss occurs immediately at transfer — pretensioned beams with multiple strands lose additional prestress from elastic shortening caused by other strands.
Inputs
Fps Mpa
Internal force per unit area (Pa or MPa). Must stay below yield strength in service.
Eps Gpa
Internal force per unit area (Pa or MPa). Must stay below yield strength in service.
Ec Gpa
Reference formula or conversion factor shown for context.
Fcgp Mpa
Internal force per unit area (Pa or MPa). Must stay below yield strength in service.
Results
modular ratio n = Eps/Ec
The proportional relationship between two quantities.
elastic shortening loss Δfps (MPa)
The decrease or degradation from the baseline.
loss as % of initial prestress
Internal force per unit area (Pa or MPa). Must stay below yield strength in service. Beyond yield: permanent deformation. Beyond tensile strength: fracture.
Δfps = n × fcgp
Sample size or count used in the calculation.
typical elastic loss
The decrease or degradation from the baseline.
remaining prestress (MPa)
Internal force per unit area (Pa or MPa). Must stay below yield strength in service. Beyond yield: permanent deformation. Beyond tensile strength: fracture.
