Simulate Early, Simulate Often... In Rhino
CFD
Hello;
I am an architect and recently had a look to the Version 1.5 with hydrostatic loads. Personally, I aim to analyze the wind loads.
I wonder if there will be a CFD add-on for the Scan & Solve in the future. I also would like to ask you if there is a method with the current features of the Scan & Solve that I can apply for computing the wind loads affecting a building by some approximations.
Thank you.

HI:
Wind velocity is usually converted into a velocity pressure or wind force
according to a specific standard or code which would be a required
load condition according to the building code in effect in the jurisdiction
in which a building is to be errected.
The calulation is usually based on the projected area of a structure at 90 degrees
to the wind flow. I could dig up some example calulations for this, if it is helpful.
To apply a wind load in SnS you would calculate manually the wind pressure on
the building and then apply this as a pressure load.
Thx,
Bob

No Problem.
Computational fluid dynamics could be used to determine the flow patterns
around a group of building like in a down town core. These places produce
weird gust patterns.
The strength of the building in regards to a wind load is explicitly stated in the building codes.
Would you like some examples?

Thank you again, Bob.
The document seems to be very helpful!!
Best wishes,

I can put together a wind calcualtion as it is done in
North America and post it for you. I won't get it done till
the weekend. For a retangular building its fairly straight
forward. I have no idea what wind codes would be the law in
Turkey. I presume it has something to do with the European Union and
ISO.

Hi Bob;
If it won't take your time, this would be great! I work on "not" standardized building geometries, but your calculation would definitely be enlightening. The location does not matter for my study now.
Thank you very much.

HI:
Well Im pretty much a workaholic so I dont mind helppeople out on here. Once in awhile I get a good question.
I will crunch some numbers and run a simple example in
SnS for posting. Im learning SnS slowly. Its really affordable.

The first thing we would want to do is to determine the
maximum wind speeds that we want to design for. This should
be listed in your building codes or I found this really cool
site:
http://www.atcouncil.org/windspeed/
which provides wind speed based on latitude and longitude.
If you own a GPS gizmo for your car, so you don"t get lost
which I do have since I am truly bad with directions,
this site is for you.
Thx,
Bob

HI:
We are looking at Wind Loading as published by the American Society
of Civil Engineers (ASCE).
Im actually working on some simple building models now. Id like to analyse an oil drilling
structure in SnS and upload the results. I will post that when I am successful.
