These portal frames were first included in the 2006 IBC and IRC. Method PFH- Portal Fram With Holdowns The method was originally tested with straps clamped to a steel test bed to simulate the embedded holdown straps. The straps were nailed to the wood with enough nails to mimic a 4,200 lb. strap anchor. The original test report is APA T2002-70.
Braced Frames vs. Portal Frames
https://hp-eng.com/2021/08/braced-frames-vs-portal-frames/
If you are designing a structure for a roof load or wind load, a portal frame may be the right choice. The design reduces the bending movement in a beam, which enhances the overall rigidity of the entire structure. When designing a portal frame, it is particularly important to pay attention to joints and bracing.
portal bracing - Structural engineering general discussion
https://www.eng-tips.com/viewthread.cfm?qid=422676
Portal frames are moment frames and can be found in almost any book on structural analysis. They typically exhibit more drift than a braced bay, so the drift usually governs if you have finishes or cladding that are sensitive to movement. As for modeling, you can experiment with pinned or fixed bases. malikasal (Structural) (OP) 21 Mar 17 14:03
