overstrength factor - AISC

[knelli]

Hi,

I'm studying for the S2 exam and have very little experience in seismic design.

Where in the AISC seismic provisions is it specifically discussed when to use the overstrength factor?

I am studying using the IBC SDC manuals, Williams Seismic and Wind examples and also have the AISC Seismic Provisions.

Are there rules of thumb when to use it? Is there a reference out there that discusses this topic in a sensible way?

Is the overstrength factor discussed in concrete design (PCA notes or others) too?

Thanks!
