The Weatherstone Riding Ring is an 80 x 200ft indoor riding rink with a glue-laminated wood and steel space truss. The structure is made up of a linear series of "splayed" trusses, a kind of 2.5 dimensional structure, that makes a diaphragm truss of the lower roof plane and carries smoothly around the end dome. There is no large "header" truss at the half dome end, as is common in these structures. Instead the dome leans into the rest of the barrel-like structure, with the thrust and pull carried by the diaphragm truss. A deep lightweight truss is used at the end to handle possible out-of-balance snow loads. A "clerestory truss" also distributes uneven loads and provides a failsafe in case a steel rod fractured accidentally. The double rod design is equilibrated by a double pin plate.
