Gazebo for War Veterans on MUH Premises in Prague, Czech Republic

Česká Skalice, Czech Republic
A new gazebo on the premises of the Military University Hospital in Prague was inaugurated on Monday, May 12th 2014. The gazebo is primarily a gift for war veterans.
Dlubal Software customer Ing. Zbyněk Šrůtek was responsible for the structural design and analysis of this timber structure.
The circular gazebo with a diameter of 16.4 m is radially divided into 25 sections.
The 140 x 400 mm frame beams come together at a circular solid wood ring with a radius of 1.1 m. Every other beam is supported by a column in the internal ring of columns. Along the perimeter every beam is supported by 140 x 260 mm columns (hidden connections).
The two beams at the main entrance are supported by two adjacent frames. Because of the unique structural design of the central ring assembly, it was possible to produce this compression element solely from the standardized glued laminated timber sections. The individual segments, including the connection points for the particular beams, were manufactured using CNC machines.
The design is different from the common practice in which the central solid ring would be made of a steel weldment and covered with timber for visual reasons.
Tension in the perimeter is transferred by the external ring of the 25-sided polygon. Here the timber parts are connected with a system of embedded metal sheets by selfdrilling dowels. The spatial stiffness in the roof plane is secured by the allover boarding which consists of roofing battens and sterling boards (OSB). Steel ties stabilize the structure in the vertical plane. The structure is anchored to the reinforced concrete foundations by hidden steel footings.
The structure was awarded the Timber Structure of the Year 2013 in the category Designs - Experts' Choice.
