Design Method
Splice Joints
Due to the need to make long span trusses from shorter lengths of timber, butt joints called SPLICES often need to be introduced in the top and bottom
chord members.

These joints, like all other nailplate joints, need to be properly designed in accordance with the above factors. Splice joints will normally occur in positions
between 10% and 25% of the panel length in which the splice occurs for triangulated trussed rafters. In other frames and when splices are outside of the code 'zone' the software will design the splice to resist shear, axial and moment forces. Some typical joint details are given in figure 25.
