Estructura de la Nave Industrial para Diagonal 80

 30 Enero 2012
La prioridad a la hora de resolver la estructura del proyecto ha sido la de conseguir una planta totalmente diáfana sin soportes intermedios. Para ello, se dispone la estructura portante en toda la alineación de fachada conformando pórticos de gran rigidez, gracias a su geometría triangulada.

Para salvar la luz existente entre ellos se han empleado vigas Fink, que debido a su disposición geométrica en planta, mediante triangulaciones, conforman dos jácenas Warren en los bordes que confieren a la estructura la rigidez necesaria para contrarrestar las acciones horizontales de viento. Tipologías estructurales La estructura vertical consta de dos pórticos de fachada, formados por pilares metálicos que nacen inclinados en cimentación en forma de “V”, ascienden con directriz recta y se juntan nuevamente de forma triangular para sostener la cubierta. En la dirección transversal de la nave (la de menor longitud), existen dos núcleos rígidos de comunicación que arriostran la estructura frente a las acciones de viento en dicha dirección. En el otro plano no se considera necesario ningún arriostramiento debido a que la disposición geométrica de los pórticos sustentantes confieren gran rigidez a la nave en esa dirección.

Como estructura horizontal se ha elegido una estructura metálica con forjados de chapa colaborante en todas las plantas, a excepción de la cubierta, donde se ha optado por una cubrición de paneles sándwich ligeros in situ a partir de chapas de acero plegado y aislante. El forjado colaborante irá conectado con las correas longitudinales de 6 m de luz, que se apoyan en las vigas principales o vigas Fink, de manera que los perfiles trabajan como vigas mixtas, lo cual repercute en la dimensión de dichos perfiles aligerando considerablemente la estructura. Con la misma finalidad (reducir la sección de acero necesaria) el forjado colaborante también se conecta con las vigas principales. El forjado colaborante de canto 16 cm. 7.70 cm, de altura de greca y 8.30 cm, de capa de compresión. El espesor de la chapa será de 0,88 mm. En la cubierta para contrarrestar los efectos debidos al viento se han colocado arriostramientos en cruz de San Andrés formando vigas verticales en algunos de los planos verticales de los núcleos estructurales que contienen las escaleras. El acero estructural usado en toda la obra será del tipo S 275 JR.

Mecanismos y elementos especiales

Como elementos especiales encontramos las vigas Fink, empleadas para cubrir las grandes luces que tenemos entre soportes ya que la propia arquitectura de la nave busca una planta diáfana, por lo que los pilares únicamente aparecen en fachada. El comportamiento estructural de estas vigas se basa en el trabajo conjunto de una viga metálica superior y un tensor inferior, para contrarrestar las deformaciones. El tendón inferior contraresta las cargas de peso propio, que se compensan tensándolo hasta que recupera la flecha alcanzada por las solicitaciones debidas a cargas verticales. 

El tensor ha sido roscado mediante manguitos, acortando su longitud, una distancia tal, que ha provocado una contraflecha capaz de contener la deformación propia de la viga. El cordón superior está formado por un perfil metálico HEA y el cordón inferior es un tensor doble de acero B 500 SD.

TEDx: Hedonistic Sustainability / Bjarke Ingels

28 Enero 2012

In this video Bjarke Ingels shares his enlightened view on Hedonistic sustainability, challenging the misconception that one must give up a portion of their comfortable lifestyle in order to live sustainability. Ingels counteracts that delusion with examples that illustrate the possibilities of sustainable buildings and cities increasing life quality. He encourages architects to embrace their expanded roles of becoming “designers of ecosystems” by creating a world where our presence is not seen as detrimental to our environment through the integration of our “consumption patterns and leftovers” into our natural world. Ingels is optimistic as he shares Hollywood’s copy of BIG’s Denmark Pavilion for the Shanghai 2010 Expo in Iron Man 2. Ingels states, “If Hollywood starts ripping off sustainable architecture to portray science fiction it could be a sign we are moving towards Hedonistic sustainability.”

New Headquarters Of J&A Garrigues / EDDEA

20 enero 2012

Garrigues, the law firm with the most tradition and prestige in Spain, has promoted during 2011 the move from it’s old headquarters in Seville to a new more emblematic location in the center of the city with the objective of renovating the image of it’s offices.

The building, situated in one of the principal accesses of the city, is located on the Avenida de la Palmera, a main artery designed with the Iberoamerican Expo of 1929 in mind, forming part of a complex of offices designed in the 80′s, and with approximate surface area of 6,000 sqm., and four stories tall, counts on four entrances, public areas, interior distribution and an image that were all inadequate for the current needs of the firm, in terms of function and distribution of space, requiring a reconditioning and addition of the latest building technologies, and an image in accordance with the professional profile of the work space.

In this fashion EDDEA was tasked with the all inclusive turnkey project at a fixed price, with a limited time frame (Fast Track), including an audit of the building prior to the rehabilitation, drafting of the project, construction including installations, furnishings and integrated project management, right up to the final stages, legalization, and post construction maintenance management.

In terms of the design decisions, in dealing with an office building with a structure that was present both inside and out, the greatest difficulty of the job consisted in the elimination of those elements that impede a clear interpretation of both the access points, and communication between spaces. In this sense the work encompassing the atrium becomes one of the most important aspects of the rehabilitation, giving prominence to the space, the light and unification of colors and materials, so that through it’s sense of a scale we can clearly identify the companies signature.

Lastly, the program was distributed, prioritizing the public use of the access floor, dedicating the greatest part of its space to reception, attention of clients, meeting rooms, and lecture halls. On the rest of the floors we find the work spaces, ordering the closed offices around the perimeter, along the length of the facades and leaving the central spaces for open work areas, support lounges, archives and communications.

Best And Worst Global Airport Terminals

20 enero 2012

Posted by Airport International's Global Correspondent on 20/01/2012 - 12:20:00

Long-established travel guidebook publishers Frommer's has issued data on what it considers the world's 10 best airport terminals. On the flipside, it also names the 10 worst and, as per US national USA Today, the ratings take into account 'cleanliness, services, on-time departures, navigation and the ease of getting to and from a city's center'.

On this basis, Saudi Arabia's Hajj Terminal, at King Abdulaziz International Airport, is judged the cleanest, slickest-running and most accessible airport terminal on Earth.

Constructed specifically for use by pilgrims flocking to the country to participate in Hajj - the Mecca pilgrimage - it features an iconic tent-shaped roof and can accommodate up to 80,000 passengers at any one time.

Best Airport Terminals

The full Frommer's list of the best airport terminals is as follows:

• Jeddah Hajj Terminal - Saudi Arabia
• Leifur Eriksson Air Terminal - Iceland
• Seoul Incheon Airport - South Korea
• Wellington "Rock" Terminal - New Zealand
• JFK Airport Terminal 5 - New York
• Singapore Changi International Airport Terminal 3
• Marrakech Menara Airport Terminal 1 - Morocco
• Madrid Barajas Terminal 4 - Spain
• Carrasco International Airport - Uruguay
• Bilbao Airport Main Terminal - Spain

Worst Airport Terminals

At the other end of the scale, Terminal 3 at New York's JFK is considered the world's worst and it's one of no less than four US airports represented in the worst airport terminals list. The same airport's Terminal 5 does make the top ten, but it's the only US airport facility in this position.

Now over 50 years old, JFK Airport's Terminal 3 is set to be knocked down in three years time within a programme that's seeing Terminal 4 being expanded. Originally constructed for the sole use of Pan American, it presently supports Delta Air Lines operations.

In the words of Frommer's, this terminal presents scenes of ‘endless immigration lines in a dank basement, an utter lack of food and shopping options, three crowded and confusing entry points, and hallways that could have been designed by M.C Escher for vomiting international travellers out onto an underground sidewalk with no cabs available'.

Frommer's ranks the world's 10 worst airport terminals as:

• JFK Airport Terminal 3 - New York
• Manila Airport Terminal 1 - Philippines
• Moscow Sheremetyevo Airport Terminal B/C
• Jomo Kenyatta International Airport - Kenya
• Paris' Charles de Gaulle Airport Terminal 3
• Queen Alia Airport - Jordan
• LaGuardia Airport Terminal 5 - New York
• Newark Liberty International Airport - Terminal B
• Beauvais Airport - Paris
• Chicago Midway Airport

PANalytical / DHV architects

19 Enero 2012

PANalytical is the market leader in analysis systems for x-ray fluorescence (XRF) and x-ray diffraction (XRD). To further enhance its leading position in x-ray systems and tubes, a new production facility for x-ray tubes has been designed in Eindhoven. The new building must not only be able to realize future growth, but must also further increase operational efficiency.
The building has three floors that are related to the production process; pre-assembly, assembly and final assembly. In total this process covers about 2,000 m2. Stacking activities results in a compact and clear building where the spatial layout is defined by the production process. Adjacent to the production floors resides the research facility (1,330 m2). Here are new products being developed and tested. Thanks to an atrium, the research facility has direct visual contact with production floors, without disrupting the specific room conditions.
In terms of structure and installations the building is modular in design. The high purity system is modular as well, making ‘plug & play’ connections possible. Combined with light separation walls and a complete quick-response sprinkler system, the building is extremely flexible. Functions are fully interchangeable thanks to the uniform structural concept in terms of vibrations and floor load.

The mechanical systems largely determine the energy use for the building. Therefore we explicitly sought to apply energy-efficient solutions. The most notable solution is the heat pump which reuses the heat generated by the process for building heating. This allows most of the building’s annual heat demand to be covered by this process energy, resulting in a significant reduction of natural gas consumption and associated CO2 emissions.
Achieving a ‘stacked’ research facility had the advantage that the site could be relatively small. The use of two submersible pumps instead of the traditional sprinkler tank was even more space saving. Therefore it was not necessary for PANalytical to purchase additional land.
All functions relating to the production process (discovery – development – production – sales) are located around an atrium. The atrium acts as a communication tool and guarantees synergy between departments and, in particular, between people. All supporting activities, such as meetings and relaxation, take place inside the atrium.
The facades of the building are a reference to the refined machines featuring the end product. The orange accents mark important moments in the facade. The exterior of the building creates extra tactility and refinement via the use of different types of profiled cladding.

Childcare Centre Maria Enzersdorf / MAGK illiz

19 enero 2012

An influx and increasing birth rate in the community situated to the south of Vienna called for the creation of more, particularly state-of-the-art child care facilities. Therefore a competition tender submission for a new child care centre was issued in 2008. The existing 19th century ‘Gründerzeit’ school was to be extended by eight primary school classes, a after-school care club and a kindergarten with kitchen.

The association of architects MAGK illiz won the competition and was awarded the tender. The draft of the project team MAGK illiz breaks up the construction into L-shaped bodies which are interlaced in such a manner that different places and free spaces to play in and for learning are formed in the interstices.

Good orientation and quick ways for children and adults are provided by a simple routing system between the functional areas of the two-floor ensemble. The new main entrance to the school is also the assembly hall and connects the existing school building with the new building. The façade is developed as a ‘pixeled’ white envelope. Format and joining patterns of the “window pixels” meet the current utilisation needs whereby the rooms at the back can be interpreted from outside and the recall value of the individual building sections is enhanced. The façade surfaces alternate between smooth and rough plaster which, particularly in grazing light, creates a vivid impression.

Unlike the high-contrast façade, the design of the interior rooms is characterised by varying, finely tuned colour and material combinations. The differing design of doors, cloakrooms and wall panels in an individual range of colour for each area of activity facilitates finding the way and increases their identification, particularly for the children. The cloakrooms of the children’s groups are covered in wood and meander like snails shells into private niches.

 “Pixels” protrude into the corridors and from the façade; they are used by the children as nests to read and to cuddle up in. All activity areas have green and free surfaces. The playground used for breaks turns into a climbing and adventure scenery by its dazzling orange rubber surface, the roof terrace with the smoothly concreted surface becomes a race course. Crèche and kindergarten form a common one to two floor patio which forms a settled pacified centre surrounded by play corridors, multi-purpose and action rooms. The colourful door and ventilation elements of the room-high glass façade allow a for an event room to emerge which can be used flexibly. There is a two-floor loggia of a white-coated welded grid and coloured glass pain curtain to the west of the group rooms on the left, in front of the kindergarten. It complements the monolithic character of the building and is both a sunshade and fall-protection. Depending on the viewing angle, the façade appears anything from transparent to closed, from the interior, however, it embodies a protective second envelop, allowing the smallest children a glance into the greenery and conjures colourful spots of light in the room.

The material and construction concept is characterised by the high standards imposed on ecological sustainability. To ensure the building period was speedy, the new construction was setup in a composite construction method with a solid core as storage mass and a prefabricated, high-insulation envelope of timber frame construction, of solid wood panel structure respectively.

The entire new building complies with passive house standards, the aim of which is greatest ease and comfort for the user at lowest possible operating costs.. With an innovative ventilation concept it is possible to achieve a minimisation of costs with regard to the operating times of the mechanical ventilation. For this purpose the classrooms and group rooms are aired by transverse ventilation via acoustic slot openings across the corridor zones without noise from the corridor being transported into the classrooms. This concept also technically ensures that overheating in summer is prevented temperatures dropping at night. Thanks to efficient cost control the overall budget could also be used to redevelop and renovate the existing gym in the scope of this extension. Furthermore, the circulating strip lights could be renewed and provided with circumferential horizontal, partially movable sun protection louvers.

concept

The childcare centre of MAGK illiz is characterised particularly sensitively by the traditional, small dimension structure of the surroundings. The broken building volume is so interlaced that it by no means competes with the environment.

first floor plan

Together with the existing classrooms, the new primary school, the crèche and the kindergarten form one of the largest childcare centres in Lower Austria after a mere period of three years needed for planning and building.

El primer bosque vertical

17 enero 2012

 Bosco Verticales de Boeri Studio es un edificio de alta densidad que experimenta con la integración del paisaje con la fachada arquitectónica. Las dos torres se encuentran actualmente en construcción en Milán, lidiando con el concepto de regenerar el paisaje perdido por la ciudad junto con mejorar la habitabilidad de los edificios actuales. Ambas torres, de 80 y 112 metros me altura, tendrán una capacidad de 480 arboles medianos y grandes, 250 pequeños, 16.000 plantas y arbustos; El equivalente a una hectárea de bosque.

Esquema
Las plantas viven en la fachada al igual como lo hacen en un ambiente natural. Las plantas actúan de manera similar a como resultaría una ‘fachada inteligente’, éstas filtran el polvo del aire, absorben el dióxido de carbono y liberan oxigeno hacia el exterior, mientras también otorgan sombra y un microclima que refresca los meses de verano.

Esta ‘recolonización’ urbana con especies biológicas además de generar mayor biodiversidad, crea un ambiente seguro para animales que encuentran en estas especies refugio y alimento. Esto lleva vida a la ciudad, vida típicamente exclusiva de parques y jardines. Además Bosco Verticales contribuiría a la mitigación de gases tóxicos, además de purificar el aire atmosférico.
© Boeri Studio
La selección de plantas y la distribución de las mismas se realizó con extrema minuciosidad, de manera de aprovechar al máximo el sistema de irrigación.
La forma de los edificios fue elegida para ayudar a prevenir la expansión urbana, proporcionando a los residentes un paisaje privado dentro de sus apartamentos y ofreciendo las mismas ventajas de vivir en una ciudad. La propuesta es el equivalente de 50.000 metros cuadrados de bosque y casas de familia en un entorno de expansión.
