Framing Problems
Introduction
In a wood-frame house, wall framing includes the studs, plates, blocking and strapping, interior partitions and wall sheathing.
Also included are framing members around openings, jack studs, cripples and lintels.
Most homes in North America have walls that are platform-framed, resting on the floor system below and supporting the floor system above. In some instances, balloon-framing is still used where wall framing is continuous over a number of floors, without interruption at floors as shown in Figures 8a and 8b.
