stress-relieved strands
i'm trying to track down a stress/strain diagram (or curve equations) for 270k stress-relieved strands. does anybody know where this might be available?
the strands i am performing the analysis on were stressed in 1985/1986, have the material specs changed since this time?
thanks in adavance.
check out our whitepaper library.
why do you need the stress strain curve for? you may try pci design hand book 3rd or 4th edition for this!
as far as material goes, stress relieved strands are no longer readily available. all strands now are low lax. aashto std specification contains equations for loss and
i'm determining the capacity of an existing structure for the purpose of issuing repair recommendations. the oldest pci handbook i have is the fifth edition.
i'll check into aashto's specs though, thanks.
