Horizontal Bracing
Horizontal Bracing
(OP)
I have an existing building in a high seismic area, that we are renovation. In order to get the metal roof decking to withstand the shear loads, I calculate that 18 ga deck with (11) welds along the sidelaps (1500 plf capacity). I doubt however the existing roof deck is this guage.
Has anyone ever used horizontal braces? I was thinking of attaching angles or other sections to the bottom chord of the joists, since it may be difficult to run through the webs. Are there any good design guides for this? I assume the design would be just simple T or C members, right?

RE: Horizontal Bracing
I had a project about 25 years ago that the X-bracing was missed by the fabricator and the construction review caught it. The wall was brick veneer on steel stud and the stud and brick work had been installed... used sheet material with pop rivets to replace the metal angle bracing. First time I ever used pop rivets for a structural application.
