Need help with "Delta cg" from PCI Lateral Stability of Precast, Prestressed Concrete Bridge Gir

[Ron247]

I have been trying to follow the design examples in the PCI publication noted above but I cannot find how to calculate the value referred to as "Δcg". It appears to be function that needs certain variables but I do not see the function or formula anywhere in the document.

Is anyone familiar with this?

"Recommended Practice for Lateral Stability of Precast, Prestressed Concrete Bridge Girders CB-02-16-E"


Thanks in advance.

Are you talking about this Δcg?

That appears to be it. I could not find it in the pdf version of the text that I have. I looked with my eyes and used a pdf search routine. Never found it.

Thanks a million.
