In a steel truss an upper longitudinal beam and a lower longitudinal beam are interconnected at their respective ends by vertical posts, and between their ends by a plurality of mutually intersecting, obliquely extending struts and ties only. Each end post is composed of two parts of substantially equal lengths, which are interconnectable end to end, and each strut and tie is composed of two parts, which are interconnectable at the intersection between them, whereby the truss may be factory-made in sections of moderate size for convenient transportation to the building site, where the assembly of the same requires only a minimum of work. |
