The behavior of these trusses is more complex than that of conventional vertical trusses. They act, in unison with the purlins, columns, and other components of the structural grid, as part of the vaulted roof design, carrying different loads and offsetting different forces than those normally encountered in truss construction. The truss pairs are rotated 45 degrees about their longitudinal axes, putting them at 90-degree angles to one another. This configuration enables them to help support the weight of the structure while resisting both horizontal and vertical forces. Triangulated in both directions, the rods handle stress reversals from tension to compression forces.
Turnbuckles enable careful adjustment of the rods.
Custom steel-plate connectors were used at the joints. The bottom chords of some of the trusses support rails for operable acoustic doors. These doors allow for subdivision of the hall, thus accommodating different sporting and agricultural society events.
