ASCE 7-10 wind loading over canopy structure
ASCE 7-10 wind loading over canopy structure
(OP)
Hi,
I am designing the canopy structure which comes under the 1st floor balcony slab (assume that canopy is under the slab exposed to wind pressure in which canopy is not exposed to positive wind pressure from top).. the canopy is supported by the top slab (balcony slab).
my query is how do i consider the positive wind pressure acting on the canopy as it is not directly exposed to it.. ?
I am referring ASCE 7-10 for the wind load calculation and to find the cp value for canopy i am referring to NJ COOK journal on wind loads acting on canopies attached to buildings.

I have attached the canopy section drawing as you can see the canopy is cladded by composite panel under the slab.
According to ASCE i am getting wind pressure as 1.464 kPa and Cp value (from NJ cook text book to be +0.93 & -1.3) but because of slab on top i dont think we need to use full positive pressure coefficient..

I agree with you david and ron, its better to consider full Cp value neglecting the shelter factor because of top slab but is it ok if i consider the canopy in category B than in C because the building is near to the sea and its a high rise building (100 meter high which is surrounded by other high rise buildings)

I would like to know is it necessary to consider the internal pressure for the lateral wind load calculation for designing this canopy...
Please help..

May I know what is the material of the canopy? Is it steel?
If it is, how is the connection of the canopy to the balcony slab? Is the balcony slab an existing structure?
Thanks.
