Truss
STRUCTURE & PHYSICSintermediate
Definition
A structural framework of triangulated members that spans large distances efficiently. The triangular geometry means every member is either in pure tension or pure compression — no bending — making trusses very material-efficient. They are common in roofs, bridges, and long-span floors.
Example
The Crystal Palace in London by Joseph Paxton (1851) used repetitive timber and iron trusses to span the exhibition hall — one of the earliest large-scale prefabricated structural systems.
