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

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

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

(OP)
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?

(OP)
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.
