	Historic Bridges of Iowa - Construction Types
		In addition to classifying metal truss bridges by name, their form is further distinguished by the location of the bridge deck in relation to the top and bottom chords, and by their structural behavior.
		The Pennsylvania (Petit) truss modified the Parker truss by introducing sub struts or sub ties, which are members of the truss acting to resist or transmit stresses, respectively.
		The original form of a Warren truss was a series of equilateral triangles, and as such, represents one of the earliest, simplest truss types.

	truss project
		The truss that we decided to use was a Warren Truss.
		Warren trusses are symmetrical and can be identified by their composition of equilateral or isosceles triangles.
		Another reason that we chose the Warren truss was because of the small number of welds.

	trusstypes
		In the simplest type of truss bridge the two trusses are essentially one dimensional, stiffness in the third dimension being provided by the deck.
		Those trusses that are deeper in the middle than at the ends have been designed in response to the variation of bending moment along a beam.
		In the USA, wooden trusses were often built in the form of covered bridges, the wooden roofs and sides being added for protection to the bridge from the elements.

	Truss bridge - Wikipedia, the free encyclopedia
		A truss bridge is a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads.
		Truss bridges are one of the oldest types of modern bridges.
		Truss bridges became a common type of bridge to see built from the 1870s through the 1930s.

	Bridge Types - Truss (Site not responding. Last check: 2007-10-13)
		Trusses are comprised of many small beams that together can support a large amount of weight and span great distances.
		The small size of individual parts of a truss make it the ideal bridge for places where large parts or sections cannot be shipped or where large cranes and heavy equipment cannot be used during erection.
		The Pratt truss (illustration #3) is identified by its diagonal members which, except for the very end ones, all slant down and in toward the center of the span.

		When I did the test I suspended a strap around the middle of the truss and hooked a pail to it by a hook; I used gravel to weigh down the bucket.

		The Warren Truss didn't break on the bottom, but got a long splinter on the bottom.

		The Nebraska Bureau of Roads and Bridges eschewed Warren truss configurations in favor of the Pratt truss throughout the 1910s and 1920s.
		Completed that year, the bridge was comprised of three 100-foot, polygonal Warren pony trusses and three approach spans.
		When a devastating flood swept away one truss and one approach span in 1935, the bureau replaced the lost truss with one of identical design fabricated by the Omaha Structural Steel Works and constructed two new approach spans on the south and three on the north.
