Precast-prestressed Spliced Girder Bridges
Elongation

When the jacking force, Pj, is applied at the stressing end, the tendon will elongate. The elongation is computed as

where

D = elogation
Ep = modulus of elasticity of the tendon
Apt = cross-section area of the tendon
Px = tendon force at distance x from the jacking end
