Biothing pavillion consists of serval self-modifying trasformative curves under the control of various grasshopper components. The structure of this sort of outcome is mainly contributed by fields components which can make strips transformed or folded and be structured into various shapes. Many ideal frames, structures ot patterns could be pricisely controlled and transformed into some incredible outcomes. The huge potentials in strips and folding make it an attractive feild to explore. They also help expolre the usage of material. The material itself can not only be used as structure, but also used as patterns, ornament and expressions of design ideas. However, there are some limitations on fabrication. As we all known, the technique of 3D printing has not been improved over the last dacade, still restricting within a small area of printing platform. If this pavilion is going to be built in reality, it could not be fabricated as an entirety but splited into many pieces, which could affecting the visual experience. It requires many cutting-edge techniques to connect the different parts of this pavilion making it as smooth as its digital model looks like. Another concern is about the material. as we see in the picture on the right side, softness and flexibility are essential for strips and folding. But these strips are also used as structure, so that strengthness and capacity of loading are also required. And it resulted in a limitation on the choice of materials.

B.2 Case Study 1.0 - Criteria

The criteria of seletion is about whether this variation can contribute to my design. The proposal for my design is a functional pedestrain stuctrued and ornamented by strips. It requires flexibility, mesh-like, capacity of structure and creates space for functions. These four selections could contributing my ideal visual experience and the essential functions of my design. The appearence of the design is a pedestrain above the water level with a flexible frame above it. The main function is about rubbish recycling, so mesh structure is essential. And other important is that if it can be achieved as ideal model by existing technique.

This struture is like a basic foundation for the pedestrain without blokcing water flowing or fish swimming. It is a simple, easy and efficient structure. And with the flexibility of each single mesh-like support stud, a floating wave pedestrain surface could be achieved.

This mesh structure based on spin vectors create oppotunities for tranformation of the pedestrain surface and the frame above the pedestrain. As a frame above the pedestrian, it can control circulation and give people visual enjoyment.

This mesh mainly works for the recycling function under the water. With a appropriate space between each mesh curve, it will block the rubbish efficiently and creating pull force by water to reshape the frame.

This structure might work for both above and under w a t e r. I t m i g h t b e u s e d as supporting structure to create an up-and-down platform and give inspritions for futher design.

This pavilion is an entirely bending-active structure made of extremely thin, elastically-bent plywood strips and this project focused on material-oriented computational design, simulation and production processed in architecture.[5] This project compeleted a successful research on material behavioural features in parametric principles. the plywood peices were totally computational outcome from design to frabrication. Also, the meterial behaviours like the capacity of bending were tested accuratelly by mechine. It's a very impressive project can inspire people to explore the meterial behaviours and think about potentials of entirety project.

B.3 Case Study 2.0 - Reverse Engineer

1. draw 2 closed curves

2. divide curves into segements

3. cull the groups an CRVVP to ev

em into two d then use valuate them

4. use weave component 5 . i n t e r c o p o l a t e a n d to create the wave strips extrude

B.3 Case Study 2.0 OUTCOMES

The script of this pavilion is quite complex for me to use and understand at the beginning. However, after I finished this part, I found I got a deeper understanding of algorithmic thinking, computational design and material behaviours. The wave strips is similar with the original but it much rougher than the original components. I directly shaped the strips into waves but the original used connection and the capacity of bending of the material. I didn't take the material behaviours into consideration and I was not materialoriented but structure-oriented. The keys of the original are bending materials and connection. But mine made structure and shape as the goal. I will pay more attention on the relationship between material and stucture and material behaviour in my future design.

B.4 Technique: Development OUTCOMES

These two variations are the most successful ones for my proposal. The arc frame is one of the most obivious and important features for the entirety. Iteration 3 - 5 showed the above water structure, which is a pedestrain covered by a series of arc strips. The end of the arc strips should be extended into the water and form a mesh to block the rubbish. Iteration 8 4 showed the ideal arc structure, which can be shaped by the pull force of water aroused by the volume of rubbish. However, it is very difficult to make a continuous entirety like that, the only thing can do is to focus on connection. That aroused more issues like how it can be connected to the platform to make them like a smooth entirety and how to maintain the movement of the frame.

ITERATION 8 - 4

B.5 Prototypes

This connection is very similar with ICD pavilion, which consists of bending strips by connecting them intersects. The flexible material provide convinience and oppotunities for various forms. However, this poly sheet is too thin and soft resulting in the unstable structure.

The circular joint plate with fillisters cut around its edge provide oppotunnities for various structures and provide inspritions for connections. The plate can also be as the pedestrian or tool to control circulation.

The strips could be shaped and connected by each other and create volume facade and structure. this is very important for my design, which meets the requirement of lightness, smoothness and flexibility.

Thicker poly material might be suitable for the frame. But this type of connection is a bit too flexbible and might not esay to control the shape. The high temperature and strong wind can affect its shape.

B.6 Proposal Site Analysis

Image source from google map

Dights Falls is formed by an artificial weir built on a natural rock bar and is one of the most famous site of Merri Creek which is a part of lower Yarra area. However, the water quality around Dights Fall is a big issue, which is yellow-brown and muddy with terrible smell and rubbish in it. This site is a good example to show people the problems that poor environment might arouse.

Goal to achieve

- visual appearence to show the pollution of the water by collecting rubbish - make people feel the issues living in a poor environment by blocking or adding the difficulties of the circulation and movement.

How the Merri Creek was polluted? - rubbish from human, like pastic bags, plastic bottles - dangerous chemical spill - polluted stormwater drain - soil erosion (washed by storm and cause slow flow)

statistics from http://www.melbournewater.com.au/waterdata/waterwaydiversionstatus/pages/merri-creek.aspx

The stream flow depends on the rainfall. After the storm washing, the stream cannot carry the soil or dirt and becomes slow, resulting in terrible smell.

B.7 Outcomes

Part B pushed me forward on my algorithmic skills and research skills. By researching on those successful precedents, I developed my computational skills and have a deeper understanding of algorithmic design. The computational design is quite vital today cause it has great potentials and can make many ideal design into reality. Through this period, I know more about digital fabrication and how the digital model turn into reality. There are many issues to concern about to achieve the precise ideal outcome by existing technique. It seems like the existing technique cannot catch up with digital design and become a big limitation for fabrication. People have to think about the connection, the material and the structure. However, due to this limitation, many new ideas and approaches can be developed. Aonther important outcome is about algorithmic thinking. Before this part, I thought it's fine to make a digital model without parametric approaches only if I can make the shape I want. However, after the research on ICD Pavilion 2010 and those interations, I understand that the value of pricise control and the algorithmic logic thinking. Parametric design also helped create various iterations by changing only one small statistic or component, which inspired me more ideas and help me refine my design. I will apply parametric approaches to my future design and help myself explore more potentials.
