New construction of a roof for the Brünnli ice rink, Hasle b. Burgdorf
2005
A roof for the previously open ice rink was to be built over the existing civil defense facility. The building lines allowed hardly any leeway in the design of the roof shape. Limitations had to be observed not only in the ground plan, but also in the section.
The project
The aforementioned constraints led to the chosen structural form with a truss spacing of 5.20 - 7.00 m.
The construction method
The trusses are designed as an underbraced, buckled 3-hinged frame, which is additionally extended on one side by a post and bracing. This allows the bending moments in the stem to be reduced. The secondary structure consists of rafter purlins designed as Gerber girders. The trusses stand on clamped steel supports; the roofing was made of corrugated sternite.
