3Screws in the field of the panel shall be installed 12 inches on-center (305 mm) unless otherwise shown.L106 Concrete Filled Landing - Ledger Angle Connection to Concrete Wall. Plywood and OSB screws shall be a minimum 8 by 1-inch (25 mm) flat head with a minimum head diameter of 0.292 inch (7.4 mm). Install horizontal bridging in stud system.Framing screws shall be 8 by 5/8-inch (16 mm) wafer head self-drilling. I am looking for advice on the best way to model this section in order to determine the reactions at the screws (caused by this eccentric loading).Anchor tracks to jamb studs with clip angles or by welding, and space jack studs same as full-height wall studs.
At this point, I do not believe that the screwed connection will not work for this application - I will push for the welded connection.Thank you all for your advice. That this approach is not advisable.Similar to what KootK mentioned, our initial thought regarding this connection was that the top screw would pick up most of the tension load and the other two screws would not pick up much of the load until the top one failed. I was hoping to figure out a way determine these reactions, since it would help with convincing the EOR, etc. The EOR suggested that we could predrill the holes in the angle to avoid this issue - I don't believe that they want us to screw from the interior side.I have attempted to model this angle/connection configuration in RISA in an effort to get an idea of the reactions at the screws, but I am not sure that the results I have seen are accurate. Thanks.RE: Connection of Steel Brick Lintel (For Support of Brick Weight) to Cold Formed Metal Studs KootK (Structural) 5 Dec 14 22:05KootK, Hokie66 - we were also concerned about the problem of connecting from the 3/8" angle to the thinner stud flange.
It is possible to install from the inside of the stud (may need a extension to the driver bit) at the web/flange interface and result in greater pull-through capacity as you mobilize the TEKS head through the cold-formed stud.
