inclined curtain wall

inclined curtain wall

inclined curtain wall

(OP)
Hello!
I'd like to model the effect of the curtain wall on a single story steel structure (about 4.5 m high) with walls inclined outwards.
I wonder if in such a case the curtain wall's self-weight will rest on the ground, or should I impose it onto the structure, at the anchorage?
I guess, that a part of its self-weight will rest on the ground, and another part is overtaken by the structure. (The same with the wind load.)
Have you ever designed a structure with outwards inclining curtainwalls?
In a general case for a single storey steel structure with vertical curtain walls is it a usual practice to design the curtainwalls as resting on the ground, or as resting on the structure via anchorages - or resting on both?

What is your opinion of the following structure?

I assume, that the curtain wall has a kind of pinned support both at the bottom and at the top. In a conservative manner maybe I'd say 50% of it's self-weight can be imposed onto the structure. I'd take also 50% of the wind load imposed onto the structure at the anchorage.
Am I wrong?

Sorry for these dump questions... I'm not experienced yet.

Thanks for your patience and help in advance!

RE: inclined curtain wall

Where the anchorage occurs will dictate how the loads are transferred to the structure. For instance, it is common for a single story curtain wall to bear on a floor slab and not transfer a gravity load to the structure. The curtain wall will almost always transfer lateral shear loads (from wind) to the structure around their attachment. Depending on the system, most loads are carried by the vertical mullions; however, horizontal members can also transfer loads directly to the structure. Check with the curtain wall supplier about the anchorage. All connections are pinned.

RE: inclined curtain wall

Good morning CEst,

Also note that the leaning wall will result in a horizontal couple at the supports under the wall self-weight. Maybe not a big deal for the structure but can be significant for the support/embed design.

regards,
Michel

RE: inclined curtain wall

Sine or cosine. - just figure out the vertical and horizontal loads
