Pavilion 19-20 is a two storey building with 24mx24m column path and 64m long beams in roof structure.

The transversal 65m length reinforced beams are supported by the tower-comlumns at 21.45m level.

They are made by steel box beams (upper chord) got from 2 HEAA 900 and reinforced in the vertical plane with 6 zinc-coated 42mm diameter high resistance steel cables.

The vertical elements are made with HEAA280 steel section, arranged in the plane of the truss, with a V shape.

The total height of each truss is almost 10% of the net length of the beam itself, while the vertical elements distance is 24m.
