Tekst: <p>If it weren’t for the blast furnaces and a few other historical relics from ArcelorMittal, you wouldn’t know that Belval was ever an industrial site. In the heart of the ‘Cité des Sciences’, the architectural firm Valentiny hvp has transformed an old 110 metre long ‘Möllerhalle’ into a contemporary university library, which opened its doors at the start of academic year 2018-2019. The original steel supporting structure of the building was preserved, treated and reinforced so that the complex could be given a new facade and composite roof. The unique synergy between old and new gave rise to a masterpiece that earned the project both the jury and audience prizes in the Steel Construction Competition 2019.</p>
Tekst: De möbiusband staat niet alleen symbool voor de circulaire economie, maar eveneens voor openheid en dynamiek. Hij illustreert dan ook het centrale thema van het Luxemburgse paviljoen: ‘Resourceful Luxembourg’. Wie het geluk heeft om tussen nu en 31 maart 2022 aanwezig te zijn op de wereldtentoonstelling in Dubai, moet dit fraaie gebouw zeker gaan bezichtigen. De unieke schil omhult een complexe staalstructuur.
Tekst: Alongside the Handelsdok in Ghent stands a remarkable construction: a compact building with a kind of giant steel pergola around it that forms a green outdoor room. The Melopee civic building is part of the Oude Dokken urban renewal project around Houtdok, Achterdok and Handelsdok in Ghent that has been in progress for more than 15 years. It includes a day care centre, an after-school childcare centre, a primary school and a community sports hall.When the project was conceived, it quickly became clear that the extensive programme for the civic building and the rather limited space on the site would not result in a classical school plan. A solution was found in the stacking of the various play areas, which led to the choice of an open support structure forming a steel outdoor room on the waterfront combined with a compact and rational 40 x 30 m school building on the east side of the site.For the slender outer room, the steel columns are placed on a 4 x 5 m grid to limit the span and thus keep the thickness of the concrete floor slabs down to 15 cm.

Tekst: <p>Het MAS (Museum aan de Stroom), een ontwerp van het Nederlandse bureau Neutelings Riedijk Architecten, is open voor publiek sinds 17 mei 2011. Het is een nieuw en opvallend landmark voor de stad Antwerpen, dat er het verleden, heden en toekomst van de stad wil in samenbrengen. Het MAS staat waar vroeger het Hanzehuis stond, het 16e-eeuwse handelshuis van de Duitse Hanzesteden. Het is dan ook geen toeval dat de architectuur van het museum verwijst naar de oude stapelhuizen, zoals de buurt er tientallen kent. <br>
Het MAS is opgevat als reusachtig stapelhuis, een verticale opeenstapeling van enorme natuurstenen koffers. De koffers zijn zo gestapeld dat ze elke verdieping een kwartslag draaien om zo een vierkante spiraaltoren te vormen. Op elk niveau kan de museumbezoeker uit de roltraproute stappen en een zaal binnenwandelen. De holtes in de spiraalstructuur zijn afgeschermd met een glazen gevel, zodat bezoekers door de grote ramen telkens nieuwe en indrukwekkende vergezichten krijgen op stad, rivier en dokken.</p>
Tekst: The TrinkHall Museum, which was created by the renovation and extension of an existing modernist pavilion dating from 1963, stands in the Parc d’Avroy in Liège. The area of the museum has now been doubled to 1,800 m2 and both the existing space and the functional extensions placed under a protective dome. Economical use of materials, compactness and energy efficiency were important considerations and gave rise to the realisation of an extremely lightweight skin in 50 mm multi-walled polycarbonate sheets. Thanks to the use of S235 steel with a span of 21 m, the building envelope has a very lightweight structure. The supporting structure has been coated in fire-resistant paint to guarantee a fire resistance of 60 minutes and the corresponding figure for the roof structure is 30 minutes. Steel was also used to finish the roof and floor edges, all internal parapets, the museum furnishings and the library.

Tekst: The new fire station in Leopoldsburg is beautifully situated in the town centre overlooking an attractive open lawn dotted with trees, including a protected ancient lime and oak . Its solid base structure is clad in curved, copper-coloured steel plates that blend in perfectly with the brick buildings that dominate the surrounding area. Given the nature of the building, it was essential that the design allowed for impeccable organisation and a swift exit every time. Covering the facade with steel was not only an aesthetic choice but also a sustainable and economical one, and the pre-painted steel sinusoidal profiles came with a three-layer polymer coating of primer, colour coat and varnish. Inside the station, a ceiling in white profiled sheet steel has been installed in the fire engine depot. In the entrance hall stands a main staircase made of welded steel stringers that function as a parapet and support the folded steel steps, all painted a striking zinc yellow.

Tekst: The new provincial government building in Antwerp is a compact and sustainable construction with its own unique identity. Solidly built, but with an elegant twisted shape and distinctive triangular windows, the tower stands out against the sky but blends in beautifully with the surrounding greenery. The congress hall, auditorium and foyer are in the base of the building, half below and half above ground, and the office block has been erected on top of this transverse section like a bridge over the roof terrace. This fourteen-storey tower has twisted design that immediately catches the eye. The congress building, designed around a steel frame, has an open floor plan with large column-free spans – just what is needed for the meeting rooms, auditorium and exhibition hall. A graceful yet eye-catching steel staircase connects the different levels. On the fourth and fifth floors of the tower, three steel trusses span the low-rise conference building beneath, whilst the outer trusses are embedded in the concrete and follow the twisted contours of the building.

Ondertitel: Vernieuwd bosinfocentrum van provinciaal domein Het Leen in Eeklo.
Tekst: Natuurliefhebbers die zich willen verdiepen in het wel en wee van bossen, bomen en hout kunnen sinds de herfst van 2019 terecht in het vernieuwde bosinfocentrum van provinciaal domein Het Leen in Eeklo. De nauwelijks zichtbare constellatie van weleer maakte plaats voor een uitnodigend geheel met een lichte, transparante uitstraling. Dankzij de integratie van een glazen serrevolume kreeg het centrum een nieuw gezicht. Bovendien werd er ook een imposante uitkijktoren opgetrokken, die fungeert als visueel baken en herkenningspunt voor het hele domein. Thermisch verzinkt staal speelde een cruciale rol in deze opvallende transformatie.
Ondertitel: Stalen brugconstructie over congrescentrum
Award: 0
Tekst: <p>Compact, duurzaam en met een uitgesproken identiteit: zo profileert het nieuwe provinciehuis in Antwerpen. Massief maar door zijn opvallende torsie en zijn driehoekige ramen toch elegant, tekent de toren – veertien verdiepingen hoog – zich af tegen de lucht en kadert hij harmonieus in het omliggend groen. <br />Op de vierde en vijfde verdieping van de toren overspannen drie stalen spanten de onderliggende laagbouw van het congresgebouw. De buitenste spanten zijn ingestort in het beton en volgen de gedraaide vorm van het gebouw. <br />De congreszaal, het auditorium en het foyer werden deels ondergronds en dwars in de sokkel van het kantoorblok geschoven. <br />Het congresgebouw ontworpen als een staalskeletconstructie, heeft een open plattegrond met grote kolomvrije overspanningen zoals vereist voor de vergaderruimtes, het auditorium en de tentoonstellingshal. Hier valt de sierlijke stalen trap op die de verschillende niveaus met elkaar verbindt.</p>
Ondertitel: Koperkleurig stalen jasje zorgt voor integratie
Award: 0
Tekst: <p>De massieve basisstructuur van de nieuwe brandweerkazerne werd aangekleed met geonduleerde staalplaten, die door hun koperkleur zorgen voor een perfecte integratie in de door bakstenen gebouwen gedomineerde omgeving. De nieuwe kazerne is ingeplant op een prachtige plek in het centrum van Leopoldsburg met zicht op een mooi open grasveld met ‘arbres aléatoires’. Uiteraard was een vlotte en veilige uitruk en een goede organisatie faciliteren essentieel in het ontwerp. <br />De gevel bekleden met staal was naast een esthetische ook een duurzame en economische keuze. De voorgelakt stalen sinusprofielen (SAB 42/960) kregen een drielagige polymeercoating (Seren Copper, Colorcoat Prisma® - Tata Steel). <br />Binnenin de kazerne kreeg de stelplaats voor de brandweerwagens een plafond in witte geprofileerde staalplaat. De hoofdtrap in de inkomhal bestaat uit gelaste stalen trapbomen, die fungeren als borstwering en de geplooide stalen treden dragen. Het geheel werd opvallend zinkgeel gelakt</p>
Tekst: 70 St Mary Axe, known informally as the ‘Can of Ham’ because of its curved shape, is an office building in the City of London. Rising to a height of 90 m, it has 24 storeys and a footprint of 48 x 40 m. The load-bearing steel structure of columns and floor beams is built around a concrete core that houses all the pipes, lifts and stairs, and the steel skeleton contains almost 3,000 tonnes of grade S355 steel. The columns are a combination of UC profiles and UCs with welded-on plates; floor beams are either welded-together sheet steel girders or UC profiles. The construction technique selected for the floor – the 33,000 m² floor plates are made of 0.89 mm galvanised steel profiled sheets filled with lightweight concrete – meant that it could be walked on within a week. Each floor comprises an average of 100 structural steel elements that took on average 1.5 weeks to assemble per floor. The roof structure is made up of 5 curved composite profiles.

Ondertitel: Hedendaags paviljoen in historisch kader
Award: 0
Tekst: <p>Het ontvangstpaviljoen van het Brugse Gruuthusemuseum herstelt de afsluiting van het eeuwenoude ‘hof’ en staat centraal tussen de Onze-Lieve-Vrouwekerk, het Gruuthusepaleis en het Steenmuseum, waardoor de site meer dan ooit een historisch geheel vormt. <br />In deze context van uitzonderlijke erfgoedwaarde profileert het paviljoen zich als een hedendaagse constructie – een exoskelet van staal en glas – terwijl de (neo)gotische vormentaal van de omliggende monumenten erin weerklinkt. <br />Het is opgevat als een gevouwen staalstructuur, naar het structurele principe van de ‘folded plate’. De dakvlakken bestaan uit staalplaat van 6 mm en de kolommen uit staalplaat van 8 mm. De grotere hellende vlakken van de luifel zijn lokaal verstijfd met 10 mm dikke opgelaste vinnen. In de verticale, kopse vlakken zorgen IPE 100-ribben voor de nodige stijfheid. De doorgedreven detaillering van de staalstructuur versterkt de architecturale expressie.</p>
Tekst: An existing 100 m long office building on the Noorderlaan in Antwerp has been given an extra storey of office space. Located next to the viaduct, this new structure was conceived as an interpretation of the existing industrial context and comprises a complex of fine steel porticos in different shapes that, in combination with CLT plates, give rise to three large, slightly sloping roofs. The combination of wood and steel with a total weight of 37 tonnes was an ideal choice and meant that the steel trusses could be anchored in the existing concrete structure. The new floor structure consists of steel girders on top of which a steel deck forms a substrate for the OSB and linoleum finishes. The exterior joinery is made up of a 265 m² steel curtain wall in which the vertical profiles run between the cladding, emphasizing the sense of rhythm. The steel porticos are finished with a fire-resistant coating.
