[EN] Transfer length is a significant parameter in the design of pretensioned
concrete members. This study reports the measured transfer
length of 15.2 mm (0.6 in.) prestressing strands. Twenty-four pretensioned
concrete beams were cast using conventional concrete. The
compressive strength at release ranged from 27 to 65 MPa (4000 to
9500 psi). Transfer lengths were determined by measuring concrete
surface strains and using the average maximum strain (AMS)
method. A new technique was developed to smooth the measured
concrete surface strains. The measured transfer lengths were
compared to the predicted transfer lengths using ACI 318-14 and
AASHTO-LRFD equations. The results indicate that the proposed
smoothing technique provides better results than the current threepoint
moving average technique. The current code equations are
conservative to predict transfer length for pretensioned concrete
members having concrete compressive strength at release greater
than 27 MPa (4000 psi). |
