Wind Calculations

[MCS Renewables]

Hi
Had our two day MCS audit this week. Three technologies produced two non conformances .

Solar PV and solar thermal ...no wind load calculations.

Having read the entire section on wind calculations I am still at a loss as to how to do the calculation and what to do with the figure when arrived at. ( Not to mention why ?! )

Any help or ideas or samples would be appreciated

Thanks

My MCS inspector passed me ok with Midsummer results regarding wind calcs

We had our structural engineer build a virtual property in his software (TEDDS) that was worse than the worst scenario we come across. We have uplift figures for all roof sectors.

The mounting system we use has been tested by BRE, so we have the failure and typical figures for each bracket.

Dividing one into the other gives us figures for configuration of mounting system.

Assessor well impressed on surveillance visit.

Dead load is unlikely to be an issue. Calc is easy.

Just watch old roofs or unusual structure/construction. That is when you need to consult your structural engineer.

Is this site still working, I can't seemed to get anything to pass. Even if I put 30 fixings per bracket, or use double the brackets we would normally use.....

It was working last night.

All the other calculations seem to work for me but not the Windload calculations. I just put 1000 brackets in and still not enough. Maybe me somthing I am doing?

Even at 2kg/fixing it gives me a fail.

I will have a quick check now but it worked on two jobs for me last night.

Thank you, been a great website all round, surprised by it not working, but the same for both me and my business partner.

That's strange it's just worked for me on a quick test.

I've just re-tried the calculator through all zones and heights and I couldn't get it to work with a building height 5-10m 10-15m in zone 4. All the other heights/zones work.

Thank you for checking, thought it might

I have even tried it on a different computer. Do you mind showing me what you input? Do you have to work through all of the roof calcs or can you skip to the Windload calc on it's own. We have touch screens that allow you to skip through to windload by swiping.

I have just tried to simulate yours

If you pm me your mobile number I will talk you through it.
