RC Shear Walls: 0.7*Ig vs. 1.0I*g
RC Shear Walls: 0.7*Ig vs. 1.0I*g
(OP)
Hello, does anyone understand why ACI 10.11.1 calls for UNcracked wall I to be 0.7Ig? Why not 1.0 Ig?
Would it be appropriate to use 1.0 Ig for the walls in an eigenvalue analysis?
Thanks!

I wouldn't change the values ACI recommends unless you take into account everything that is stated in 10.11.1. The factors the code gives in that section are alternates to doing a much more in-depth analysis. So if you want to use 1.0Ig, you have a lot more work to do.

Doing more work is fine as long as I can justify using a higher Ig.
