Wind loading from Wind Tunnel test

Wind loading from Wind Tunnel test

Wind loading from Wind Tunnel test

to: SABURO, STRESSED AND SLICKDEALS

How to input or perform to ETABS the equivalent forces (peak forces) from wind tunnel testing report as a static forces or after calculating the equivalent static net wind loading to the extension of diaphagm?

I try to look at it but cant figure it out.

thanks guys!!

 

RE: Wind loading from Wind Tunnel test

The wind tunnels usually run their analysis and give you loads in X and Y + a torsion at the center of the diaphragm based on what you provided them to test.

They also give you certain combination to use like 45% X + 80% Y + 65% Z etc which will be your load case. They typically do a full 360 degree model and give you values at 15 degree angle, which means you will have 24 different wind load cases.

More often than not, they give it to you in an excel format. I know RWDI and CPP do that. Once you have the values, you can copy paste these into etabs and done. It's as simple as that.

If you have more specific questions, post it.

Yes, WIND TECH gave us the load distribution per level at every 10 degree increment with a specific load combination in a hard binded paper. I can copy it but how/where will i paste this?

Further, after we can calculate the wind load per level of the structure, it is right for me to apply the calculated wind load to the slab boundary per level?

Thank for the usefull tips.
  

RE: Wind loading from Wind Tunnel test

You can request for a soft copy. Who is the wind consultant?

The results probably give you one value per level (typically @ the center of the diaphragm). You should apply this to at each level.

Our Wind consultants is WIND TECH, and australian based. Anyways, thank you for some tips.
