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.
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”
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.
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.
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.
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?
