Portal Frame Detail-AutoCad

This detail contains the quintessential elements that make the portal frame so useful. The knee joint takes all the loads from the rafters and purlins and transfers it down the stanchion and into the pad footing. The girts hold the walls and the purlins hold the roofing. Haunching is used for extra support for the all important knee joint. Isn't it a wonderful idea? Until next time, enjoy it...
