Canopy atop Freestanding wall
Canopy atop Freestanding wall
(OP)
Hello,
I am designing a canopy which is on top of a steel column. I am using ASCE07-10 to calculate loads. I am stuck at wind loads for this geometry. Although this is a freestanding wall, this also qualifies as lattice framework and trussed towers. I was designing it as a lattice framework but on doing some research I came across some articles calling this a trussed tower. I am not sure in which category this structure should go. Any opinions?
Thanks.

Also keep in mind: even for a open canopy.....you will have uplift and down loads for it. IIRC ASCE 7-10 (and later) covers that.

I'd apply it over all the cover. See Figures 27.4-4 & 27.4-7 in ASCE 7-10.

For the uplift/down MWFRS loads on the roof? That's the idea. For the support members (i.e. columns, etc)....I think the lattice method would be appropriate.
