Prestressing Force after Immediate Loss when Reverse Friction Effect is Considered

LaTeX Go Prestressing force after Immediate Losses = (Prestress Force at a Distance/(exp(Simplified Term*Distance from Left End)))+Prestress Drop

Prestressing Force at distance x when Reverse Friction is Considered

LaTeX Go Prestress Force at a Distance = (Prestressing force after Immediate Losses-Prestress Drop)*exp(Simplified Term*Distance from Left End)

Loss of Prestress due to Slip

LaTeX Go Prestressing Force = Tendon Area*(Modulus of Elasticity of Steel Reinforcement*Slip of Anchorage)/Cable Length

Slip of Anchorage

LaTeX Go Slip of Anchorage = Prestressing Force*Cable Length/(Tendon Area*Modulus of Elasticity of Steel Reinforcement)

Prestressing Force after Immediate Loss when Reverse Friction Effect is Considered Formula

Prestressing force after Immediate Losses = (Prestress Force at a Distance/(exp(Simplified Term*Distance from Left End)))+Prestress Drop
P = (P_x/(exp(η*x)))+Δf_p

What is Partial Prestressing?

Under the working load, if the cross section is subjected to no tension after prestressing then it is known as fully prestressed. Similarly under working loads even after the pretsress is applied if there is some tension,it is known as partial prestressing . Normally the tension portion is reinforced with mild steel reinforcement. This un-tensioned reinforcement is required so as to resist differential shrinkage temperature effects and handling stresses.
