Hangers/connections Schedule
Hangers/connections Schedule
(OP)
How do you guys usually do your connection schedule for your wood framing? Do you specify what kind of nails to use use with the simpson hanger? Or do you rely on the contractor to read Simpson catalog? What if you fasten it to a nailer or concrete instead?






RE: Hangers/connections Schedule
There are connectors made for fastening to concrete. Don't just drill out the holes in something that isn't designed for tapcons. Not sure if that's is your last question or not.

titen screws directly to the concrete. We usually only specify the connection type but I think I will start putting the fastener also.

Great question. Here are my thoughts on that issue. Generally, I only schedule hurricane clips based upon uplift forces. I recommend you schedule the appropriate nails by designating diameter and length (ex: 0.131" x 3") By the way, the penney weight designation will soon be a thing of the past. Common, sinkers, box, pneumatic, etc. have variant lengths or more importantly variant diameters. Simpson and USP do carry a 10d 1.5" nail used for joist hangers. These are often used in beam hangers! OOPS. There are huge reductions for using these incorrect nails. For your own protection and more importantly, the safety of the public, be very specific in specifying the nails.
Another issue in scheduling hangers based upon reactions only can be shown by the following example. Suppose you have a 3 ply 14" LVL carrying either joists/rafters/ or common trusses. And suppose these members are framed flush to the bottom of the beam. Based on reactions, your schedule shows a relatively small, economical hanger works for the loading. The problem here which is often missed is that all the nails are loading the beam below its neutral axis. This may lead to a cross-grain tension failure.
I designate all beam to beam connections, including nailing on the engineering drawings.
