At KootK - I haven't had to revert to providing the calc's you suggested; had always been able to rely on the published values from the catalogs. I am curious now as to how they obtain the shear capacity...
I thought about doing that and looked at ASC B-36 and Verco Type PLB-36/HSB-36 roof decks but their width is 36" instead of Robertson's which is 24". Also the weld patterns for ASC and Verco's deck are different than what's specified on Robertson's.
