The gussets top in the gambrel system above designed by the author create a three hinged arch out of each frame which simplifies the load analysis significantly.
Gambrel roof connectors.
This is the second one so me helpful hints since the connectors are flimsy until the unit is completely assembled.
Our newest connectors have been developed to make stick frame connections in roofs as intuitive as possible to ensure the construction of safer stronger homes.
Simpson strong tie ridge rafter connector an interlock provides alignment control and correct nailing locations.
For gravity loads the system is analyzed as a triangular three hinged arch the ridge connection and the two rafter to plate connections are thought of as hinge connections while the midspan gussets are treated as rigid joints.

Hardware is required at only three points as opposed to nine different joints in the roof assembly of a traditionally framed gambrel making the system considerably easier to build.
