Wooden domes, Brindisi (I)

The biggest domes in Europe

Thanks to the know-how regarding production processes and accurate management in all assembly phases, coordinated by expert engineers, Rubner Holzbau was thus able to win the tender to create two laminated timber domes to cover the bunkers of the "Federico II" Enel power plant in Brindisi. The preliminary activities at the construction site to create the first dome began in the month of December, 2013. The two bunkers will be completed in the year 2015.
The structure
The structure
The work consists in creating two geodetic domes. Each dome presents 5 main axes which are subdivided it into 5 equal sectors. The main beams have rectilinear axes and form a series of plane triangles.
The construction
The construction
The structure of the laminated timber dome rests on 40 reinforced concrete supports with a height of 6.2 m; The dome has an external diameter of 144 m and a height of 39.82 m. The ventilation turret has a diameter of 11.9 m and a height of 3.04 m, which gives  a total above ground height of about 49 m. This results in a total surface of about 16,300 m² and a roof surface of about 22,000 m².
About the realization
About the realization
As done up until now for structures of this type, assembly with progressive cantilever advancement technique is realized. Therefore, the connecting joints to the reinforced concrete works are designed and dimensioned to support loads resulting from the erection.
Made of: 6 cm X-Lam panel (3x2cm), 1.2 mm bituminous sheath and painted aluminium shingles. The elements are pre-assembled on the ground and loaded onto the supporting structure with a crane. The elements have a surface of 37m²-67m². Maximum weight = 4,800 kg.
