This shows the section running in the opposite direction to the previous section. you can see the main structural steel column that the rafter is connected to and the haunching joins onto this also. The footing detail is much the same as previous and is therefore in less detail. The girts on the left side show the cladding connection. The roofing is fixed to the purlins ontop of the rafters.
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...
