Raised-heel trusses can be annoying
We installed raised-heel trusses with bottom chord overhangs on our house. The top of the top chord is 20″ above our top plate. According to the 2012 International Residential Code for seismic zones or zones designated for winds of 100 mph, raised heel trusses more than 15.25″ have to be blocked and braced.
It has taken my dad, wife, and I about 6 work days to accomplish all of that. Right now, our time isn’t costing us anything, but lost time hanging out and relaxing, but I plan to start a house design and build company after this. A lot of time and money will be devoted to blocking and bracing raised heel trusses if I incorporate this design into any future house I build.
Attached are some pictures showing how we blocked and braced our trusses. We are actually mixing metal strap bracing with 1/2″ plywood sheathing. The walls are braced with metal strap bracing, but the trusses and blocking are tied into the walls with the 1/2″ plywood. We ripped 4’x8′ plywood in half and notched it where the bottom chords overhung our walls. The sheathing comes down about 8″ onto our walls.
Anyone have a more efficient way of blocking and bracing raised heel trusses? I forgot to mention that I am building in a 90 mph category area so I probably don’t have to do this, but with our weather getting weirder, I want to be prepared for tornadoes, hurricanes, and Godzilla.
