Braced / Return Wall Requirement
Braced / Return Wall Requirement
(OP)
The IBC Section 2308.9 in the 2009 edition covers wall bracing. Basically a return wall that is similar to a shear wall but is not necessarily a shear wall. This wall is referred to as a braced wall as it is bracing the wall running perpendicular to it. The IBC then states that you need a braced wall ever 25' or 35' depending on seismic design category.
Question - If diaphragm strength and deflection criteria are met and shear wall strength and deflection criteria are met are braced walls still required?

@Cadair - Uplift would be resisted by holddown anchors at the ends of the shear wall.
I have never used the 'prescriptive/empirical' approach, I've always done the analysis and designed the load path accordingly.

I didn't think that they were required if you did a full analysis/design but the presenter (who is not doing a very good job IMHO) made it 'seem' otherwise.
