Diaphragm girder
Definition
A secondary horizontal beam, rigid connecting piece, or structural stiffening element mounted transversally between two parallel main girders, aiming to maintain their distance constant, prevent their twisting or buckling, and uniformly distribute gravitational or dynamic loads. This element is essential in the construction of steel bridges, viaducts, and complex roof frameworks.
