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?
