Single & Double Angles for Steel Bracing
Single & Double Angles for Steel Bracing
(OP)
Both single and double angles are used for bracings in steel structures. Back-to-back double angles are more popular since the saving of connection bolt (due to double shear) and no worry about the entire buckling around weakest axis z (in an angle to x or y). Can anybody advise your rule of thumb and experience in using single angle bracing?
Thanks in advance.

RE: Single & Double Angles for Steel Bracing
you try single angle until angle size 80x80x8
if it exceed more than this you should better use 2 angles back to back for economy
Note:- 80x80x8 are dimensions for european sections and
are 80mms height of both legs and 8mms thickness of
both. (i do not know it equavliant in american
sections)
another solution is to use two angles forming star shape

I have never used star shape, it is just for painting convenience, I guess. But it traps dirt as well, and needs more connection bolts. In addition, the interconnection is not as easy/good as back-to-back angles. The local buckling of single piece between interconnectors may be larger concern.
Whether use angle, WT, HSS, or WF can be another big topic. It is determined in many cases by client's or fabricator's preferences without structural reason.
