Scan-and-Solve for Rhino

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

Thank you, 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 help

people 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.

Bob

Sounds good, Bob!

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:

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.

Hi Bob;

Thank you very much!

Best wishes,

Sevil
