Prestress strand - calculating debond length based on slippage
Prestress strand - calculating debond length based on slippage
(OP)
Is anyone familiar with a method for calculating the effective debonding of a prestress strand based on its slippage?
The only reference I've found are the strand stress-strain curves, but using these will only let me calculate a prestress loss over the entire length of the member, whereas an effective debond length will only be on the end of the slippage, and give a more accurate result.
Thanks
