The History of the Prestressing Strand Development Length Equation

PCI Journal, 1993
A research study was conducted to determine the history of the strand development length equation. The strand development length equation was first introduced in the 1963 ACI Building Code and was adopted by AASHTO in 1973. The original research that formed the basis for the derivation of the strand development length equation was conducted at the ...

Excessive Strand End Slip in Prestressed Piles

ACI Structural Journal, 2000
Recently, inspectors of the South Carolina Department of Transportation observed a strand end slip problem involving 610 mm (24 in.) octagonal piles being cast at the Socastee Bridge location near Conway, South Carolina. From measurements taken in the field, it is apparent that the problem of excessive initial strand slip is independent of pile shape ...
