Plastic Modulus vs Elastic Modulus for Steel Design
Plastic Modulus vs Elastic Modulus for Steel Design
(OP)
For beam design, the green ASD manual used the elastic section modulus S for steel design. The 13th AISC edition uses the plastic section modulus Z for steel design.
So you're getting an extra strength capacity per the new code, which relies on the "outer" fibers yielding until the whole section is utilized effectively.
What are your thoughts on this?

Everybody complains about the 2005 equations being longer, but all the items such as this are out in the open so that everybody should know the underlying assumptions.
