I can't quite figure out the units for the breakout strength coefficient in section 6.5.4.1 of the PCI Design Handbook, 6th ed. I'm guessing it should come out to lbs/in^2. Is there a specific unit associated with the 3.33 value?
I also can't quite seem to find what the lambda factor is. Is it 1.3 for lightweight, just like in rebar development? Or is it the 0.85 for lightweight, and 0.75 for sand lightweight? 0.85 and 0.75 make more sense since they would lower the overall capacity in this case.
Thanks in advance!
