A timber roof structure was recently constructed over an existing open-air ice rink in Jelgava, Latvia. The project located on Pasta Island serves as a multi-functional building for recreational, cultural and social activities.
Because the skating rink was located next to an existing pedestrian bridge and building, the shape and appearance of the roof needed to blend well with the surroundings. For this reason, a curved glued-laminated timber roofing was chosen.
The roof structure includes a partial frame supported on multiple columns. On the lower side of the structure exists a tapered column which is rigidly connected to the curved roof beam. On the higher side, a pinned tapered column supports the structure. The lateral support system includes three spans of circular rod X-bracing.
The total height of the roof amounts to 24 ft 3 in on the higher side and 9 ft 7 in on the lower side while the span measures 74 ft 2 in. The building is enclosed at the lower side with a membrane structure.
In 2018, the roof structure received 1st place in the "Timber Building" category at the annual "Building of the Year" awards in Latvia.
