Hello,
I am working on STAAD.Pro V8i and I can read in the help manual, for the Japanese codes 2005 steel design thatthe equation for the Allowable bending moment stress correction factor C is written:
C=1.75 - 1.05 (M2/M1) + 0.3 (M2/M1)^2
I am using a 2011 version of the "Design standard for steel structures - Based on Allowable Stress Concept - " standard book, and in the book, the equation is written:
C=1.75 + 1.05 (M2/M1) + 0.3 (M2/M1)^2
I am a bit confused so I would like to ask if:
a- This is a typing mistake of the help manual,b- This is how the software was coded, c- The standard has changed and the software is using a new version of the equation,
or is there an other reason fo this discrepancy?
Thank you very much.
