Questions for American Towers's steel structural member info

Questions for American Towers's steel structural member info

Questions for American Towers's steel structural member info

(OP)
I am reviewing ATC's tower calculation. On ATC's drawing, there are some structural info not familiar to me.

For example, Leg Members: PLA 50 ksi 9*3/8"; PLA 50 ksi 7 7/16"*3/8". I can guess the material is 50 ksi but what are the member size by 9*3/8" and 7 7/16"*3/8"?

Also, Diagonal members: DAE 36 ksi 1.75x1.75x0.1875. I can guess it refers to 36 ksi single angle 1 3/4 x 1 3/4 x 3/16. But for PLA 36 ksi B Lacing and PLA36 ksi D Lacing, then I do not have any idea what member they are.

Could anybody help me? Thanks...

I think the dimensions give the width of the angles in three dimensions. The 9*3/8" means the angles is 9"x 9" with a thickness of 3/8". The 7 7/16" means the angle section is 7 7/16" x 7 7/16" with a thickness of 3/8"
