Wood trusses were used by the Greeks and Romans, more than 2,000 years ago, in large public buildings. http://construction.hostzi.com Archaeologists have dated the earliest of these to the 5th century BCE.
The modern wood truss made of wood and metal gusset plates was developed in the 1950s, was widely used by the 1970s, and is common today in both new construction and remodeling. Steel bar joists are common is both buildings with masonry load-bearing walls and in buildings with structural steel frames. For more information on these common types of trusses, visit www.fireengineering.com and search for "trusses."
