skos:scopeNote
Assemblages van onderdelen (zoals balken, stangen of staven), vooral wanneer opgesteld in een driehoek of combinaties van driehoeken, om zo een onbuigzaam geraamte te vormen (om een gewicht over een groot gebied te ondersteunen), dat niet kan worden vervormd door de werking van een van buitenaf inwerkende kracht zonder dat een of meer van de onderdelen vervormen. Ensambladuras de miembros (como vigas, barras, o barras) dispuestos típicamente en un triángulo o combinaciones de triángulos para formar un marco rígido (como apoyo de una carga sobre un área) que no se puede deformar por el uso de una fuerza exterior. In engineering, structural members such as beams, bars, or rods, usually fabricated from straight pieces of metal or timber, that form a series of triangles lying in a single plane; based on the principle that a triangle cannot be easily distorted by stress. Trusses were probably first used in primitive lake dwellings during the early Bronze Age, about 2500 BCE. The first trusses were built of timber. The Greeks used trusses extensively in roofing; trusses were used for various construction purposes in the European Middle Ages. A major impetus to truss design came in the development of covered bridges in the United States in the early 19th century. Cast iron and wrought iron were succeeded by steel for railroad truss bridges. Trusses are also used extensively in machinery, such as cranes.
