Shielding effect of one column on another for in plane wind calcul.
Shielding effect of one column on another for in plane wind calcul.
(OP)
There are 3 columns in a plane braced frame spaced at 6 m. In order to calculate the total wind force on frame when wind is in the plane of frame,I get the force coefficient for single column(I section) as 2 . This multiplied by depth of column(500)*height(16m)give me the total force on a single column.For total force on frame do I multiply this value by 3 or will there be some shielding effect of upstream columns on second and third columns

For ratios up to 4 there is a shielding factor of 0.2, interpolate between.
Dinosaur also raises a valid point.

given by Dinosaur that I have never considered shielding in such cases.Confirmation from both of you have definitely
given me confidence.
