What does trussing mean?
Trussing is the framework or arrangement formed by trusses, the triangulated structural members used to span roofs, bridges, stages, and similar constructions. By arranging members in triangles, a truss transfers loads to its supports while controlling bending and distributing forces through the structure. The word can also refer to the act of fitting or securing something with such a framework. In a second, chiefly literary use, trussing means binding or restraining a person or object, as when a captive is tied up. These meanings share an underlying idea of holding something in place: a truss supports a structure, while ropes or straps restrain a body. In engineering contexts, trussing is normally a mass noun, so one speaks of roof trussing rather than individual trussings. The term is most closely associated with construction, architecture, and civil engineering, but the binding sense survives in formal or literary prose. Knowing both senses helps distinguish technical descriptions of a building’s supporting members from figurative or historical accounts of people being tied up.
A supporting framework or arrangement of structural members, especially one forming part of a roof or bridge.

Usually uncountable in modern technical usage.

Trussing is normally an uncountable noun, but the rare plural trussings is occasionally used for distinct systems of trusses.
"The archive lists separate trussings for the bridge and the roof."
A truss turns an enormous load into a web of triangles, helping roofs and bridges hold their shape.

Etymology of trussing
Trussing is based on the English word truss, from Middle English truss, borrowed from Old French trousser, meaning “to bind or fasten.” The verb’s binding sense reflects that older meaning directly, while the structural sense developed through the noun truss, a framework of beams designed to carry loads. Old French trousser is commonly traced to Vulgar Latin *trussare, although its deeper origin is uncertain; trousse and trousseau belong to the same French etymological family.
