Abstract: A combined wooden floor joist and foundation wall stud truss and construction process is disclosed whereby a wooden foundation wall and floor trusses for a framed building are erected simultaneously. The individual truss members include elongated floor joist members that mount all weather treated foundation wall studs by means of truss clips. The studs have side surfaces that are coplanar with side surfaces of the floor joists. A number of the trusses may be secured to a footing along a treated sill plate, and tied together by the sill plate and by treated plywood sheathings nailed to the studs. A rim joist can also be used to tie the individual trusses together into a completed frame unit including foundation wall studs ready for sheathing and floor joists ready for subflooring. The process basically involves preparation of the footing, placement of the sill plates, and installation of the truss units.
