RE: WIND LOAD CALCULATION
The answer depends on a number of different factors.
1). Are you trying to calculate overall structural wind loading? Or wind loading on individual cladding panels?
2). What type of structure is it? Tall building? Shelllike structure?
3). If you have some sketches, pictures or descriptions of the structure, please share.

RE: WIND LOAD CALCULATION
We have checked, IS 875, ASCE 7 ,but unable to find the exact pressure coefficient.
Please help.

Yes the structure is like fenced enclosures without roof. Unable to find any reference towards calculating the pressure coefficient, to calculate the exact wind load. Can we do with 1P and forget about any internal pressure.
Dear dauwerda,
I think the structure is not similar to freestanding walls and solid freestanding signs.Any other suggestion , please.
RE: WIND LOAD CALCULATION
@engineeringofcivil  what does 1P mean? D you mean taking the pressure coefficient at 1.0*roof height dynamic pressure? This approach would be wrong.
If the wall connects to the floor, then you take s/h = 1...
The net force based on your wall aspect ratios will be around 1.3 to 1.45.
To put this into context, if you had a building and considered no internal pressure, the windward and leeward pressure coefficients would AROUND +0.8 and 0.5, respectively. Therefore force coefficient would be 0.8(0.5) = 1.3 (similar to the free standing wall case).
So it is perfectly reasonable to use pressure/force coefficients for freestanding walls, especially given that you likely do not have significant blockage directly behind your walls (do you have any architectural visualisations of your building?).

Had to use it in the past for rooftop applications in the past for rooftop telecom enclosures.
