AS3995 - Drag Forces

AS3995 - Drag Forces

(OP)
I have a vertical stack (chimney)centrally placed inside a triangular lattice tower. Having modified Cde to take account of this internal ancillary, can someone advise if Fd as defined in 2.2.6(2) results in the total wind force the tower including the force from the internal stack? The only difference between 2.2.6(1) and (2) is Cd and Cde. Az the projected ara of the tower sections, remains the same. The clause appears to read like this, however I am concerned I should be adding separately the wind load from the internal stack to the figure in 2.2.6(2)

RE: AS3995 - Drag Forces

Cde is the coefficient for the tower with ancillaries and 2.2.6(2) is the Fd for the tower with ancillaries; no additional drag force is applicable.

apsix, thank you for that.
