Cantilever Steel Canopy

[fatihash]

I need to design a cantilever steel canopy , span 8.48m and width 2.2m

Plese help me to calculate wind load as per ASCE 7 , I calculated qh as 0.932kN/m2 .

How to choose wind pressure coefficients as per ASCE .??which figure should I refer for coefficients?

Please help , I am designing canopy for the first time .

Thanks

Please provide a sketch and the version of ASCE 7 to which you must comply.

Do you have a more senior engineer available to review your work? We can only provide general advice here. We cannot do a detailed review of your work.

For the roof uplifts/downloads....see Figures 27.4-4 & 27.4-7 (for MWFRS) and Fig. 30.8-1 (for C&C) in ASCE 7-10.

At first glance it may appear these are for roofs with a slope.....but you can use them for when the slope is 0.

I worked on the design of a curved, cantilevered canopy 2 years back; 55 ft (16.8 M) long x 9 ft (2.7 M). Attached are the provisions from ASCE 7-05 (Client's standard)and NYC Building Code that we followed.

Attached a staad model of the canopy .
Length 8.48 m
width 2.28 m
Code ASCE 7-05
Canopy location is at first floor level at 5.5 .which wind coefficients should be considered ?

You have to look at the angle the canopy makes with the building. We used 6-11B because our canopy was almost flat coming off the building.
