PROJECTED AREA FOR WIND LOAD ESTIMATION FOR ELECTRICAL SUPPORTS
PROJECTED AREA FOR WIND LOAD ESTIMATION FOR ELECTRICAL SUPPORTS
(OP)
Hi Engineers,
I am to design a steel support 1.5m high to carry three electrical panels and a spread foundation as attached. I am looking at using the MWFRS (ASCE 7) procedure in estimating the lateral force. Any ideas on how to estimate the projected area?

Panel "B" is 550 x 450 x 450 (W x D x H); all in mm
Panel "A"&"C" are 360 x 110 x 250 (W x D x H); all in mm

You know how large each piece is. Since you're describing them as panels, I presume they're solid objects.
You presumably know in what orientation they are mounted.
Visualize or draw said pieces in said orientation as viewed by oncoming wind. There's your projected area.
