SHIELDING FACTORS (Ksh) FOR MULTIPLE FRAMES

[sdz]

AS/NZS 1170.2:2011, TABLE E2, SHIELDING FACTORS (Ksh) FOR MULTIPLE FRAMES
For wind at 45 degrees, frame spacing ratio 4.0, the values of Ksh look to be incorrect. Certainly they cant be obtained by interpolation from adjoining values.

Can you confirm this and what are the correct values?

sdz,
I would agree, the values appear to be incorrect.

I would email john Holmes and see if he can help

Well spotted...!

Yes it looks like that row in Table E2 was transposed incorrectly in the 2002 edition from the equivalent column in the 1989 edition. Nobody had spotted that before.

The correct row should be : '1.0 1.0 1.0 1.0 1.0 1.0 0.9 0.8'

Fortunately we have a correction amendment coming out shortly in which that can be corrected.
