Dlubal customer merz kley partner, situated in the Austrian town of Dornbirn, was responsible for the structural analysis and used RSTAB for it.

Structure

The new building, which opened in autumn 2020, comprises the hall including a gym with bleachers and several multifunction rooms, as well as an equipment room and changing rooms on one plane. An essential design element of the hall interior consists of ten trusses made of high-strength beech-laminated veneer lumber, which were connected in pairs, forming a spatial structural system. The utilization of this building material enables a low effective depth due to the cross-sections, which are as slender as possible. The sturdy boxes, having a span of about 1,181 inches, were clad with light-diffusing multi-wall polycarbonate sheets to ensure maximum daylight. With cladding on the sides and on the top using cross-laminated timber, these trusses weighing 24.251 tons each rest firmly on the columns, providing bracings for the structure without applying steel diagonals.

When prefabricating the trusses, self-drilling dowels were used and the assembly became easier and more precise due to a special setting tool. All other fasteners used in the rather hard timber had to be pre-drilled due to the high material density.
