Cracked Shear walls

Cracked Shear walls

Cracked Shear walls

(OP)
Hi everyone,
Can anyone give me some guideance on how to account for cracked section properties in my SAP2000 shear wall model? I believe it has something to do with f11, f22, f12 but I cannot find any literature on what range of modifier to use. Your help would be greatly appreciated! -EJ

RE: Cracked Shear walls

If the wall is modeled as a membrane type area, apply reduction factor to "set modifiers" in the f11, f22 directions. If the wall is modeled as a shell type, then apply modifiers to the f11, f22, m11, m22, and m12 directions

Hey stressed, thanks for the quick reply. I saw those modification factors while going through the program and its accompanying documentation. Although, I am still unsure of how to use them properly. Say for instance I want to account for cracking by reducing my gross moment of inertia, Ig, by 70%. Would setting the area modifiers to 0.7 be acceptable?
