What Terrain Category?

What Terrain Category?

What Terrain Category?

(OP)
Can the engineering community help us resolve a fairly simple question? The attached pic is for a site in region A4, Victoria.
Its for a 10m high circular tank with a 3.5m diameter.

If you were designing it what terrain category would you take as a rule of thumb if using an Md = 1.0 ie not considering wind direction

2, 2.5 or 3? This will help a colleague and I resolve a discussion and allow one of some bragging rights for the day.

I say TC 2-2.5 he says TC 2.5-3.

Your assistance is much appreciated. Thanks!

RE: What Terrain Category?

When in doubt, I always use the more open terrain category to be conservative.

From the attachment, I would say you are not protected sufficiently from all sides to use a less open terrain condition.

RE: What Terrain Category?

I would say TC 2.5.

The commentary to AS1170.2 has illustrated examples of the terrain categories if in doubt

RE: What Terrain Category?

Is that an airport next door? if so I would suggest that you would struggle to justify more than 2.0.

Exactly my thoughts rowingengineer.

RE: What Terrain Category?

2 on the airport side, 2.5 everywhere else.
