Clerestory roof
Clerestory roof
(OP)
What would be some concerns with this style roof in a moderate seismic region with high wind (US VI)? I'm thinking diaphragm irregularities and dealing with shear transfer, maybe some ductility issues with columns. I'm just looking for some ideas or advice on what to watch out for, feasibility, solutions or how you dealt with something similar.

Vertical push/pull reactions from overturning.
Concentrated horizontal reactions at the point of the diaphragm penetration.
Of ten they want to have windows all around so you have to have cantilevered posts to take the lateral load from the clerestory roof (think unresolved bending moments).
May be some local wind concentrations on the cladding also.

What I was looking at was a truss framed with a clerestory on one side like so: pic
My concern was how the diaphragm would behave and how that would affect seismic response and calculations, but I wanted to get some opinions on this.
Thanks again.

I figure this is steel and not wood since you mention column ductility. Are the lateral supports around the perimeter or at the interior also?

Where I come from, what you show is called a skylight and not a clerestory.

Yes I have heard them called that as well.
