2. Introduction
• One of the major goals of this presentation is to describe
different types of Hybrid Trusses and mention their proper
uses in the field of Architecture
• Hybrid Trusses: It is a type of truss, which is a combination of
two or more types of trusses which are used to provide more
functional yet stable trusses according to the need.
3. Queenpost/Kingpost Hybrid
• A combination of two most famous trusses i,e. Kingpost Truss & Queenpost Truss which
results into a highly stable truss along with a central storage place that we may call “The
Attic”
4. K-trusses
• K-trusses, limited to just a handful of states, never gained widespread acceptance, perhaps
because they came on the scene when truss bridges were falling out of fashion. A full K-truss,
with diagonals forming the "K" shape at all of the panels (except the hips), is easy to classify
This truss is a hybrid of Parker Truss.
5. Pratt/Warren Truss
• A Missouri company, Miller & Borcherding, developed this truss as their specialty. Is it a
Queenpost? The Missouri Historic Bridge Inventory calls these bridges a "hybrid
Pratt/Warren design.
6. Parker/Camelback Truss
• For through trusses, most sources draw a distinction between Parker trusses and Camelback
trusses. A Camelback is a Parker with exactly five slopes, usually with a flat top that extends
across multiple panels.
7. Baltimore/Warren Trusses
• The Arkanas historic bridge inventory classifies this as a Baltimore truss. With the flat top and
subdivided panels, this makes sense. But look closer: the diagonals form an "A" in the center.
Across all four panels, the main diagonals alternate: the hallmark of a Warren, and not a Baltimore
(Pratt), truss. So is this bridge really a Warren truss with subdivided panels?
