Prestress Loss (PCI Design Handbook Method)

Prestress Loss (PCI Design Handbook Method)

Prestress Loss (PCI Design Handbook Method)

(OP)
Hi!

PCI Design Handbook includes 'Anchorage seating loss' as one of 'sources of stress loss.'
Does its formula TL(Total Loss)=ES+CR+SH+RE include this seating loss?

Most design programs calculate prestress loss automatically.
Does it consider seat loss generally?

If a member is very long, this anchorage loss is not much and can be ignored.
What is your 'personal' border line of which per cent you can ignore?
How do you consider this problem in practice?

Thanks!


RE: Prestress Loss (PCI Design Handbook Method)

Looks like a formula applicable for pre-tensioned strands without friction and seating losses. For post-tensioned member need to include those.
