Timber Roof Structure

Because the skating rink was located next to an existing pedestrian bridge and building, the shape and appearance of the roof needed to blend in well with the surroundings. For this reason, curved glued-laminated timber roofing was chosen.

Structure

The roof structure includes a partial frame supported on multiple columns. On the lower side of the structure is 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 overall height of the roof is 7.4 m (24.3 ft), with a height of 2.9 m (9.5 ft) on the lower side; the span width is 22.6 m (74.1 ft). On the lower side of the hall and on the roof, the building is closed off by a membrane structure.

In 2018, the roofing was awarded 1st place in the "Timber Building" category at the annual "Building of the Year" awards in Latvia.
