Rule of Thumb Wind Loading
Rule of Thumb Wind Loading
(OP)
I need some rule-of-thumb per-square-metre wind-loads. I have been using 1kN/m2 for some time but I have never checked its "accuracy". May anyone help me please?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

I use 20 psf for main force resisting systems and 25 to 35 psf for components and cladding, depending on the componets location in the building.

wind pressure p in psf, wind speed v in mph
p = (v/20)^2

You can't compare one to another like this... The Canadian code may require a gust factor, however the wind sample period, or perhaps the percentage value (95th, 5th, etc) could be different.
Good example: Wind loads looked really high to me when I first arrived in New Zealand, until I realised that they aren't factored and have no gust factor.
You need to be especially clear about where you practice when it comes to force of nature loading.

Once you get used to the code it takes 5 minutes.

Like others have posted, you will need to calculate the wind loads more accuratley from the code and it will depend on a number of variables such as elevation, topology, shielding etc.
I am in Australia and my rules of thumb are
Region A - 1kPa (Melbourne/Sydney)
Region B - 2kPa (Brisbane)
Region C - 3kPa (Northern Australia)
Region D - 4kPa (Port Headland - Mining Area/monsoonal)
Most of my work is in Brisbane and the numbers crunch out to 1.34kPa.
