there are many assortment of bridges in the construction industry. They include roof and bridge trusses and their structural integrity depend on their design and construction like shown below :-
Attic truss – this truss is designed with a spaced allocation to fit an attic.
Belgian truss – constructed with structural members forming a w in the middle and two consecutive n in the sides. it was designed in belgium by engineer Arthur Vierendeel hence the name.
cambered truss – it resembles a howe truss but in this case its cambered.
double fink – it has triangles stretching from the middle outside i.e double finks. it is also known as monopitch truss
duo pitch truss – it changes pitch after a certain level.
fan truss– has two v’s with an intersecting line in the middle. it is commonly used for its structurally sound
fink truss – resembles double fink but in this case there is only one triangle hence single fink.
flat truss – it is flat in nature and is commonly used in flat roofs.
gable end truss – this truss has lines running perpendicular to one another in the span of the triangle.
gambrell attic truss – has space in the roof allocated for an attic and is of gambrell nature.
hip step – the hip is stepped down in this case and one end of the triangle is flat
howe bottom chord – has a line of consecutive n’s in the middle of the truss.
king post truss – has a structural member in the middle of the triangle and a v in the middle.
pratt bottom chord sloped – it resembles a pratt bottom chord but it is sloped.
pratt top chord truss – resembles a pratt bottom but the triangles are inverted and it has no line in the end.
pratt top chord sloped truss– resembles a pratt top chord but it is sloped
queen post truss – has two perpendicular queen posts in the middle and a connecting structural member on the top and sides.
scissors truss– the truss resembles a pair of open scissors.
semi howe bottom chord – is a single pitched howe bottom chord truss.
shed truss – This looks like a howe truss with side extension.
studio vault truss- it is a normal truss with a vault in the end
vault truss – this is a truss that resemble duo pitch but has a vault.
warren bottom chord slopped – consists of may inverted v’s and a center line.
warren bottom chord – looks like warren bottom chord slopped but in this case its not sloped.
Baltimore bridge truss – has a bridge truss with intersecting structural members for structural integrity.
Bowstring bridge truss – is a bridge truss shaped in the shape of a bow and string with middle intersecting structural members.
Camelback bridge truss – it has a camel back shape with intersecting structural members.
Double intersection pratt bridge truss – has double intersection pratt structural members that crisscross one another.
double intersection warren bridge truss – has double intersection warren structural members crisscrossing one another.
fink bridge truss – has intersecting structural members from each corner.
Howe bridge truss – has intersecting members forming an x in the middle and n at the ends
k bridge truss – has intersecting members forming a k.
lattice bridge truss – has intersecting structural members forming diamonds in the middle.
Parker bridge truss – has intersecting structural members forming x’s and straight lines
Pennysalvania bridge truss – was designed in pennysalvania with American unique design
Pratt bridge truss – has two x members in the middle and two n’s members at the end.
warren bridge truss ( with verticals) – is comprised of many v members with intersecting straight lines in the middle.
warren bridge truss – looks the above only in this case there are no verticals.
