The building consists of a single- storey portal structure with a rectangular plan with dimensions of approximately 145.00 x 57.70 m and a height of approximately 21.20 m from the finished internal floor to the ridge of the roof. The building is divided into two structural parts, perfectly symmetrical, separated by an expansion joint. From the point of view of the overall static scheme, the portals are hinged to the foot in longitudinal direction in order to create a longitudinal pendular scheme whose stabilization is guaranteed by longitudinal cross braces.

Caselle Open Mall

Final design of the mall buildings.

Category: Civil buildings
Services: Final designì
Period: January 2019 – July 2020
Client: R&P Engineering s.r.l.

The new shopping centre “Caselle Open Mall” (COM) will be built in the municipality of Caselle Torinese, near the international airport of the same name. The design covers a total area of approximately 320,000 square meters and includes the construction of commercial areas for approximately 113,000 square meters and approximately 8,000 parking spots (including 7,300 covered).
Our mission covered the structural design of buildings, foundations, glass and steel roofs and connecting walkways.
All the tertiary multi-storey buildings are represented by the structural bodies that make up the “Village”, i.e. Blocks A, B, C, D, E. The Village zone is then directly linked to two other commercial macro-zones called “Food Court” (Block N) and Premium (Block M).
The Thematic Buildings (blocks F, G, H, I, L), multi-storey car parks (SQM and M3), office buildings (block S) and the Energy Centre are also part of the complex.

The static scheme is common to all tertiary buildings and multi-storey car parks: these are multi-storey metal structures with pendular posts braced by reinforced concrete cores and blades. The deck beams are made of mixed steel-concrete section with a mixed slab on corrugated sheet.
The typical column grid for commercial buildings has dimensions of 16 x 8 m with a secondary profile at 2.5 m from centres. The multi-storey car parks have structural frames measuring 16x5m without secondary beam: the floor is made up of special 22cm high sheets resting on the main beams.
The roofs of the “Village” and the “Food Court” have glass roofs of various shapes (barrel vault, lowered dome) and sizes; they are made with tubular and reticular edge profiles to contain thrust.
The Thematic Buildings have a prefabricated reinforced concrete structure.

SCHOOL RESIDENCE
The structure, intended for the accommodation of students, has two floors above ground and has a rectangular plan with external dimensions of 10.00×40.00m and includes eight transverse frames arranged at a constant distance of 6, 60m. The static scheme foresees pendular columns with concentric bracing in the longitudinal direction, while in the transverse direction it has a frame structure.

COLLAGE
The building has on one floor above ground with a plan inscribed in a square of 28.80m side. The height of the building is about 3.90 m. The structural system consists of n. 5 main professions and n. 5 subframes. The distance between the frames is equal to 7.2 m in the longitudinal and transverse direction. The static schema is a three-dimensional frame.

For the calculation of the two structures, a linear dynamic analysis was carried out with a highly amplified local seismic response spectrum considering a structure factor q = 1, and therefore they were designed to maintain an elastic behaviour.

Congress Centre “Italia”

Design of the metallic structures of the roof “Teca” and of the supporting hull of the “Nuvola”.

Category: Public Buildings
Services: Final detailed design
Period: October 2009 – May 2011
Client: Seteco Ingegneria s.r.l. Cordioli s.p.a.
Value: €25,483,659.00 (Teca) ; €8,543,292.00 (Nuvola)

The new Italia Congress Center was built in the historic Eur district of Rome, in the area overlooking Viale Cristoforo Colombo between Viale Asia, Viale Shakespeare and Viale Europa.

The design concept can be summarized in the three main buildings into which it is divided:

  • the translucent envelope, called “Teca”, consisting of glass curtain walls and roof with metal structure;
  • a double skin structure called “Nuvola” placed inside the Teca to represent the essence of the building, an ethereal suspended body in which the most evocative areas of the complex are concentrated and inside which are located: the auditorium for 1850 seats, various restauration points and support services to the auditorium;
  • a separate building called “Lama”, the hotel of the Congress Center.

  • a separate building called “Lama”, the hotel of the Congress Center.

The object of our intervention was the metal structures of the roof of the “Teca” and the metal structures of the hull which represents the supporting framework of the “Nuvola”.

The “Teca” consists of a succession of 6 transversal portals arranged at a distance of 33 m, 70 m wide and 36 m high, connected among each other by longitudinal truss beams on the perimeter and by a grating of Vierendel-type beams that support the glass roof between one frame and another. The overall rectangular plan surface (169 m x 70 m) is approximately 1.2000 square meters and reaches a height of almost 36 m. The roof was made with truss beams with a span of 33 m, longitudinally spaced by 6.25 m and supported by macro-portals. The lattices support the purlins that form the flaps of the glass roof and the lower stabilizing elements of the members; the ropes for hanging the lateral access galleries to the Cloud and the inspection walkways of the roof itself were connected to the bottom part of the longitudinal lattices.

The “Nuvola” (Cloud) is the architectural element that characterizes the project: it is an irregularly shaped volume, with an extraordinary visual effect, covered with a semi-transparent sheet that gives it a vaporous and realistic appearance. The hull is the main structure supporting the complex; it is formed by a lattice of beams (partly trusses and partly with I-section) with highly variable geometry to accommodate the irregularity of the geometric shape of the envelope. The longitudinal and transverse beams are connected together to form a single rigid body, the shape of which resembles that of a ship’s keel. The hull directly supports the floor of Level N3, the floor of the stalls inside the Auditorium, the pillars supporting the decks of Levels N4 and N5 and finally the supporting structures of the Auditorium gallery , the support ring of the Envelope of the Auditorium and the secondary structures that support the decks of Levels N1 and N2.

The project
Managing the complexity

The design required a skilful work of mediation between the natural needs of constructive simplification and respect for the aesthetic and functional needs of the work. In the roof of the Teca, the choice of the structural profiles of the longitudinal trussed beams and their node connections was fundamental to simplify the structure, respecting the geometric and shaping dimensions imposed by the architectural project and the desire to keep the grip points unchanged for the inspection walkways, the hangings of the Nuvola balconies and the support structures for the glass roof.

The roof was designed to be erected with a specific sequence that envisages the ground assembly of the structures and subsequent lifting of entire portions of the roof by means of strand jacks. This required the re-elaboration of the structural analysis to evaluate the effects of the erecting system and led to an extreme simplification of all the connection details between the elevation structures and the roof members to be completed at height.

In the structures of the Nuvola hull the complexity of the geometric shape was combined with the significant static stress of the truss beams due to the irregular arrangement of the support points and the extent of the reactions given by the overlying architectural units. We concentrated on optimizing the structural weight of the hull, obtained by calibrating a mix of trussed and I-section beams, and simplifying the structural joints between the segments constituting the main beams, the connections between the main beams and all the connection systems of the secondary structures inside the hull (intermediate floors N1 and N2, walkways and inspection walkways) and of the secondary structure supporting the fabric covering the Nuvola.
