fenestra holorib roof deck shear capacity
i'm looking for the allowable diaphragm shear capacity for a 1963 vintage 1-1/2" 20 gage fenestra holorib roof deck. does anyone have a fenestra catalogue or icbo report? the weld pattern is (2)1/2"x1" at ends, 1/2"x1"@18" at edges, and 1"dia@24" at seams. thanks!
