VIKTORIA HENRIKSSON ABSTRACT OF PORTFOLIO Architecture and engineering student

Viktoria Henriksson

Student in architecture and engineering

EXPERIENCE

I am currently attending the master programs “Structural engineering and building technology” and “Architecture and urban design” at Chalmers University of Technology and plan to finish them both in 2016. In 2012, I recieved a bachelor degree in architecture and engineering (Arkitektur och Teknik, Chalmers). The double degree I study has influenced my way of thinking in both fields, and I think that the creativity practiced at the architecture school can come well to use in engineering tasks together with the ability to present ideas in a clear, accessible way. I am very eager to learn, have many ideas, are very motivated and love taking on new challenges. I think all these qualities would be an asset for any firm and that you would find me as a good intern!

PATINA

ART AND EXHIBITION CENTRE

Chalmers university of technology, Gothenburg Team: Pär Bratt Patina is a proposal for a new art gallery in central Gothenburg. Special focus has been on materiality and adaptation to context. As an inviting gesture, the facade running along the main public axis of “kungsgatan” slowly fades out into the roof. The appearance of copper and corten changes drastically over time. The facade will slowly adapt and earn its place within the city context.

INVITING ENTRANCE

As an inviting gesture, the facade running along the main public axis of “kungsgatan” slowly fades out into the roof. Apart from making it clear where the entrance is, this also maintains the visual connection between “kungsgatan” and the “esperantoplatsen”- plaza.

Orientation - Aligning with the direction of the existing wall.

Context reference

THE BEAUTY OF AGING The appearance of copper and corten changes drastically over time. The facade will slowly adapt and earn its place within the city context. After 40 years, the ripening process is done and the art gallery will harmonise with the rusty containers and cranes of the harbour, as well as the teal copper roofs of nearby buildings.

Node points - Entrance towards lower corner at Esperantoplatsen.

North direction - the building is shaded from direct sun light by the wall. Optimum light for art gallery.

LIGHT CONTTROL The existing wall structure at the site is naturally shading the building, eliminating direct sunlight to conflict with the art. The exhibition spaces are lit only by daylight from the gridded concrete roof. This makes it possible to create a “black box” situation for all of the exhibition spaces by using a shading device situated in each grid cell of the roof.

WAVE TOWER MIXED USE HIGH RISE IN SYDNEY University of Newcastle, Australia

The relationship between the facade and the street has been studied, in order to make a building that is still a part of the exterior life, not just an isolated object. By creating a dynamic and playful facade wrapping I want to loosen up the sometimes strict relationship between the building and the surrounding street life, that comes with a flat and vertical facade. My proposal combines the benefits of a orthogonal shape and a more dynamic one, all united in one buiding. The facade wrapping becomes balconies that brings people out to the exterior of the tower. It also offers privacy as well as sun shading, making this decorative element a functional tool. The neighbourhood interaction is a quality that I kept in the tower by not screening of the balconies completely.

LAYOUT AND STRUCTURE

The tower layout is made up of units that are easy to combine with each other in order to alternate the different types of apartments. By keeping the bigger apartments to the south, the criteria of 2 hours minimum sun light each day can be reach by having windows in two directions. The structure works trough shear walls and columns that becomes thinner as the we move upwards in the building.

VENTILATION AND BALCONIES All apartments are ventilated through slots stretching from the facade to the core in each apartment. Each floor has a cantileavering slab that serves as balconies as well as sunshading. The shape of the balconies enhances the interaction of the residents â&#x20AC;&#x201C; it allows them to see down or up to another level and around corners.

VENTILATION AND BALCONIES When entering the building, the office workers or visitors will then follow the line of sight to enter either the existing heritage building (offices) or reach the office lobby and consierge. The residents however will need to turn right when they have entered the ground floor, where a curved(wave) shape wall will guide them to their residential lifts.

FLEXIBLE LIVING

STUDENT HOUSING, GOTHENBURG Chalmers university of technology, Gothenburg Team: Linn Anna Björk

“Flexible Living” is an extremely compact dwelling, still accessible with a wheelchair. Through multi-functional space and well-designed transformable furniture, the necessities of a dwelling can be fit on only 17 m2. The entrance hall is combined with the bathroom and wardrobe, while the main living room is combined with bedroom, office and kitchen. The upper floor contains storage and extra bed space. The couch is transformed to a bed, and the kitchen bench can be combined with working area and a table. Sliding door and windows in the facade creates an easy access to the exterior.

FLEXIBLE STRUCTURE

Inspired by traditional Scandinavian log houses, the structural system is designed as a massive wood construction in order to take advantage of the thermal mass. A massive structure can accumulate heat during sunny days and then emit it to the interior room when the temperatures drop during night. The walls are insulated with wood-fibre boards that are connected directly to the load bearing system. The natural vapour-permeability of the wood-fibre boards will help to transport and distribute the moisture, making it very hard to condense. This makes it possible to create an insulated wall without any plastic â&#x20AC;&#x201C; a wall that breaths and adjusts to the surrounding.

Roof Structure Roof rests on glue-laminated walls. Glue-laminated timber beams, GLT 150-200x45 mm. Insulated with isocell which is an organic insulation produced from cellulosa fibres from recycled news papers. The insulation is sprayed on at site to ensure a perfect fit and tightness. Wall Structure 80x120 mm horizontal glue laminated timber beams. GLT beams are assembled at site according to detail below. 140 mm exterior wood fibre insulation. 30 mm tar coated exterior panel. Trellis Tar coated 60x60 wooden pillars that extend the volume of the house. The trellis hold plants that will create a green wall for shading during summer. At the bottom of the wood pillars there is a space for plants in order to shade the roots of the climbing plants. Sliding door and windows Sliding door in order to easily access the exterior and open up the building. A sliding shading device is placed at the outside of the door and window to create more privacy and shade when wanted.

THE TREE

ACOUSTICAL TOWER, HONG KONG Chalmers university of technology, Gothenburg

Nature suffers from urban areas expanding at a far greater speed than ever before. The Tree aims to reclaim some of the urban space by abstracting itself to blend in with the idiom of the city. Rooting in the ground plaza, it gathers nourishment and energy from water before it majestically rises to the sky. A complex branch structure carries the simple cuboid that holds the functions of a typical urban skyscraper. Travelling upwards, the experience becomes more and more appealing as the tree structure encounters the human scale. The grammar of a tree inspires everything from the load bearing system to the finest interior detail. By planting The Tree in Hong Kong, nature will at last get its revenge.

SEPERATING FUNCTIONS By separating the different functions flanking transmission is reduced dramatically. Two load-bearing systems are created; the facade carries the offices and nightclub by a complex tree structure, while the hotel is carried by the elevator cores. Since the offices donâ&#x20AC;&#x2122;t operate at the same hours as the nightclub, it is used to add stiffness to the facade tree.

REDUCING VIBRATIONS The low frequency vibrations from the nightclub are transmitted through the facade tree structure. Due to impedance mismatch at each branch junction and material damping treatment on the load bearing structure, a natural attenuation provides sufficient vibration isolation at the hotel facade.

ABSORBING AND ISOLATING SOUND

Wood is loved due to its complex anisotropic structure and variety of uses. It has great acoustical features and is easy to work with, making it possible to accomplish predetermined design objectives. Combined with heavier materials it is also used for isolation purposes.

OFFICE The office solution is simple but smart. Logistics runs smoothly through separated areas without disturbing the concentration of the workers. Half of the space on each floor is dedicated to three open office areas that can provide different sound environments depending on the needs of the company occupying the floor. Absorbing wooden cubicles, that hold readily available functions, are used to divide the open offices into larger acoustical islands. With an intention to facilitate for workers, there is a secondary entrance through an elevator shaft isolated from external visitors.

BRINGIN THE TREE TO WORK The wooden cubicles, that separate the open office, contain meeting rooms in different sizes as well as “phone booths“, aiming to isolate the human sound source and thereby creating a better working environment. Workstations can be composed in different ways depending on the type of work to be carried out.

HOTEL Creating the impression of a tree house, the luxury hotel is carried by the two elevator cores. An atrium spanning across all of the floors, splits the plan in two and provides daylight and city view to all rooms. Arriving at the hotel lobby, one will experience the extraordinary feeling of a high-rising space, and have the possibility to transfer to the room by an exclusive atrium elevator. In addition to a reception with associated areas, the lobby floor also holds the great room and a small business centre. The hotel’s restaurant and spa areas are located in the astonishing space on top of the tree houses.

NIGHTCLUB The nightclub offers an experience that cannot be found anywhere else in the world. Elevators carries visitors to the last stop in the building, letting them enter in a lobby that reveals a magnificent view of the city through dense load bearing branch structure climbing the facade. The nightclub is constructed as an isolated box with four floors serving as five parted spaces for events as well as ordinary restaurant- and bar activities. The spaces include a lobby with double roof height, a panorama bar with scenery in three directions, a multipurpose room for big events, and a rooftop bar with an adjacent roof terrace.

GRID CHAIR FURNITURE DESIGN

University of Newcastle, Australia As part of the course “Furniture, form & function”, I designed and produced a chair. The chair is parametrically designed in rhinoceros and grasshopper. In grasshopper I created a program in which you can load any shape, generate the “grid” and cutting sheets (in .dxf ) for laser cutter or CNC router. In the course, a folio and construction drawings according to Australian standard was created. Ergonomic studies was performed before the final chair design was produced. Before I left Australia, the chair was sold online.

VORONOI ENCLOSURE FROM 2- TO 3 DIMENSIONS University of Newcastle, Australia

The overall idea of the design has been to create a three dimensional volume from a two dimensional pattern. The pattern has been generated from a set of points in 3d space, using the parametric plugin Grasshopper for Rhinoceros 3d. The number of points has been selected as a parameter in Grasshopper, making sure that the pattern is detailed enough but still not too dense. The shiny aluminium voronoi pattern is enclosing the glass bottle containing the liquid. The glass has a tint of colour to symbolise the human skin. The relationship between the two torsos is scaled accordingly to the anthropometrics of the average Swedish male and female body.

THE VORONOI TESSELLATION The Voronoi tessellation or diagram is a way of dividing space into a number of regions. It was discovered and named by Georgy Voronoi, a Ukrainian mathematician. A set of points (also called seeds or sites) is specified beforehand and a corresponding region will be created for each point. The Voronoi pattern is a natural phenomenon, found in many places such as soap bubbles, patterns on animals, cracked soil and so on. This reference to nature is meant to further emphasize to the biological beauty of the human body.

PHOTOGRAPHY LANDSCAPE PHOTOGRAPHY University of tNewcastle, Australia

These pictures were taken during an introduction course to photography. The basics of a DSL camera was studied and practiced through different exercises. At the end of the course, a series of pictures was handed in. I chose to photograph the landscape and nature in a 500 m radius from the house where I lived during my exchange year in Newcastle. Here is the result.

TRIANGULATION The theme for the 2011 initiative seminar on Chalmers was Computational design and with connection to this, a workshop was held with Chris Williams (professor at Bath University). I and two fellow students created a program, in the Java-based scripting tool Processing, that triangulate a mathematical surface from any given curve.

FORM-FINDING As a part of an evening course in virtual tools, a workshop was help with focus on form finding. By using a script in C#, a surface in the 3d-modelling software Rhinoceros could be optimized. The original and the optimized surface were analysed in MATLAB (and CALFEM) where the deflections could be shown. The result was that the optimized surface had a smaller deflection with a factor ten.

TWISTING TOWER At the end of the evening course in virtual tools, each student was supposed to create a project based on the knowledge gained during the course. My project was called the twisting tower, which is based on “Game of life“ but with time as a third dimension. Boxes are now used instead of pixels as in Conway’s Game of Life. My goal for this project was to create something that looked like a tower that is twisting around its own middle axis. The tower is build up by levels that contains information of how each cube will survive (1) or die (0) in the next level (generation). To gain this twisting effect every cube is rotated accordingly to the rotation matrix with the previous level as reference. PHYSICAL EXPERIENTS MDuring my time at Chalmers university of technology, a lot of different physical experients and workshops were held. This was a way to experience matter, space and structure. Structures were tested to their limits to understand how they work.

STUDY TRIPS

SKETCHES AND PHOTOGRAPHS Chalmers unversity of technology, Gothenburg

During my first three years at “Architecture and Egninering”, we had many study trips to see and explore architecture and structures around Europe. The work of the British engineer Isambard Kingdom Brunel was the main focus on our trip to England. During the trip we had the chance to visit two of the world’s leading offices in the art of combining architecture and engineering: Buro Happold and Foster & Partners. In thrids year we had a trip along the Swiss Alp’s with focus on bridges and constructive buildings. The trip started off in Basel where the day was spent walking around the city looking at some of the most famous Herzon & De Meuron buildings. We later divide the 30 students in the class into minivans that would take us through Switzerland, some parts of France and also Lichtenstein.

WORK EXPERIENCE INTERNSHIP

Schlaich Bergermann und Partner, Berlin After I recieved my bachelor degree in Architecture and engineering, I decided to gain some more experience from the filds by applying for internships. I got accepted to do an internship at the engineering office Schlaich Bergermann und Partner in Berlin and also at Chapman Taylor, a brittish architecture company in Shanghai. During my internships at Schlaich Bergermann und Partner, I got to work on both archtitecture and engineering tasks. During my time in Berlin, I got a deep insight in the project management of large scale projects.

SPLICE DESIGN One of the girders at a large new bridge needed to be redesigned and from this I drew the new section, calculated the area, center of mass, moment of inertia and finally calculated the stress distribution over the cross section to check if the number of bolts are enough. By looking at the different parts (top plate splice, top web splice, bottom web splice etc.) one by one, I could calculate the force for each bolt and later compare this to the maximum allowed bolt force (120 KN M30).

INSTALLATION OF MAIN GIRDERS With the FEM analysis software SOFiSTiK I created a model that simulates the erection stages when installing the main girder of a large new bridge. From this model I could now find the required movement at each support to obtain a continuous main girder. The results were collected in a short report that presented the result with some analysis and also examples of how it could be performed on site.

ANCHORAGE DESIGN The canopy is located at the exit of a costumer center in Wolfsburg, Germany and is made like a saddle surface. The form of the surface comes from an idea of â&#x20AC;&#x153;leafs in the landscapeâ&#x20AC;? with a gently curved surface with only two points of contact to the ground. The structure consists of an elliptical plane with a surface of 1600 m2 and a length/width of 55m/38m. My task on this project was to think about the connections where the cables should anchor to the compression ring. There is a difference between the points where the cables connect directly to the ring and where they meet eccentric from the ring. Calculations in SOFiSTiK was later performed to find maximum deflections.

The point where the cables connect directly to the ring: A vertical plate reaches out and connects to the cable. Eccentric connection: A horizontal plate connects the two cables. Vertical stiffeners help to handle the torsion that appears though one cable is located at the top of the horizontal plate and one at the bottom.
