Open-Air Skating Rink Roof Structure, Pasta Island, Jelgava, Latvia
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.

Arbitrary distributions of concentrated loads often occur in the load definition of beam structures.

The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.
The design of structural components at risk of buckling or lateral-torsional buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is compared to the maximal allowable deflection.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads.
Design-relevant parameters such as the stability analysis type, member slendernesses, and limit deflections can be freely adjusted.
- How can I perform a stability analysis for a tapered member?
- I have created new elements in my model. However, these are not designed. What can I do?
- Why the results of members and set of members differ in the design?
Why can I not select sets of members for the serviceability limit state design in the respective design modules? I cannot specify sets of members under the "Serviceability Data" parameters.
- I have a model of a timber building, which I have transferred from Scia Engineer and adapted it into the RFEM program. The models should be the same; however, it can only be calculated in Scia Engineer while RFEM reports singularity. How do I edit the model to analyze it in RFEM?
- How can I model a timber-concrete composite floor?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The information about the limit time for the fire resistance design R in the RF‑TIMBER Pro add-on module is missing in the printout report. Is it posssible to add this information to the printout report?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- I have defined temperature loads, strain loads, or a precamber. Once I modify stiffnesses, the deformations are no longer plausible.
