1917 RR Truss Rating

bnjneer · Nov 2, 2011

I am looking at a 1917 RR Bridge Stress sheet, and it shows the net section properties, gross section properties and "bal". Do any of you know what "bal" stands for in the stress table? I have never seen this listed before on other old plans for bridges I have rated.

Thank you.
