CENTRE BEARING TRUSS: Truss with a structural support at its centre as well as at the heel points.
GIRDER TRUSS: A truss that performs the special function of supporting other trusses.
JACK TRUSSES: Small mono-pitch trusses in a hip construction.
MONO-PITCH TRUSS: A truss that has only one sloping top chord, with a vertical edge on the other side.
MONOPLANAR TRUSS: A truss with all chords and webs assembled in a single plane (as is the case with nail-plated trusses).
PIGGYBACK TRUSS: A truss that is split horizontally, usually because of transportation
considerations, with a standard or valley truss resting on top of a truncated truss.
SCISSOR TRUSS: A truss with sloping or pitched bottom chords.
SPLIT TRUSS: A truss that is intersected by a chimney or similar vertical obstruction.
SYMMETRICAL TRUSS: A truss with the same dimensions and configuration of members on each side of the centre line.
TRADITIONAL TRUSS: A truss that is built with lapped members, connected with bolts and nails.
TRUNCATED TRUSS: A truss that is flattened at the top to suite the height requirements dictated by its position in the roof. A truss may also be so manufactured because of transportation considerations, e.g. the lower portion of a piggyback truss.
TRUSS: A triangulated combination of members and joints that forms a rigid structural component of a roof, designed to support both permanent and imposed loads.
TRUSS TYPES: Names given to trusses with different shapes and different web configurations.
VALLEY TRUSS: A truss used to form a valley in association with standard or special trusses .
VIERENDEEL TRUSS: A truss that lacks triangulation in its frame, in which complete joint stiffness must be provided.
