    Wouldn't it be both? ..I think it would be better to increase the gauge before increasing the amount of reinforcing because there would be less room for the concrete mixture to go within the formwork. 

     

    This book has a section on concrete reinforcement & its listed in the NCARB reference matrix.

    Zach,

    It could be either.  It's up to the structural engineer to determine which method is best to achieve "increase of concrete reinforcement."  That's a bit of a vague statement.

    It could be either or both at the same time.  A 4" thick slab can only contain thinner rebar (or welded wire mesh) for example.  Much larger diameter reinforcement is needed in a large foundation walls or a large concrete bridges.

    AISC has tables and charts for sizing rebar diameter and #s.  See https://www.structuremag.org/?p=14709

    Page 21-14 on Ballast also has quite a bit of info on sizing.

    Hope this helps!

    Diane - Building Construction: Principles, Materials, and Systems is not included in NCARB's reference matrix. Do you perhaps have the title mixed up with Building Construction Illustrated or Fundamentals of Building Construction: Materials and Methods?

    A word of warning to others. I've read the first two chapters of Building Construction: Principles, Materials, and Systems (you can read the first 4 for free via Kindle preview on Amazon), and some of the content conflicts with information found in other resources that are on NCARB's reference matrix - so just be aware of that if you choose to reference it. The book does have some very useful diagrams though.
