Control Tower Barcelona Airport, Spain
WINNING PROJECT - DESIGN COMPETITION
The tower structure is composed of a shaft built with precast prestressed concrete elements which materialize straight lines laying on the surface of a rotational hypar and maintaining their bearing towards the vertical axe along their length.
The tower structure is composed of a shaft built with precast prestressed concrete elements which materialize straight lines laying on the surface of a rotational hypar and maintaining their bearing towards the vertical axe along their length.
On the top a steel framed building houses the control room and the relevant services; an aluminum trussed stair is located inside the main truss.
The construction system, which was studied as integral with the design, is based on an incremental erection of the prestressed concrete hypar and of the stair case; the stair structure is used as a template for the correct positioning of the precast elements following the relevant complex spatial geometry and in return it is braced by the already completed tower parts.
The joints between the precast elements are realized by means of post-tensioned vertical and horizontal bars and of tixotropic mortar injections.
The tower compound is completed with a annular two storey base building which features precast concrete frames and floors.
