If I have a typical braced frame where the braces are double angles, if I use a spacer plate with a through bolt at mid-span to connect the double angles, can I consider them braced at mid-span for compressive purposes? I would assume that I could because one is in tension and the other...
I am designing an LED sign on HSS tube columns (similar to what you see in front of schools). ASCE 7 says you need an offset for wind forces equal to .2 times the sign width and the extra torsion created gives me problems because the column needs a 3" diameter hole for electrical purposes. I...
