B1 Research Field
Strips and Folding
Strips and folds, as one of the most interesting pattern in architectural and structural application has been largely used in the virtual and computational design world. What makes me choose this field is the great potential and design possibility of strips and fold structural. The strips and fold structure can achieve the a fluid and dynamic outcome in an surface therfore to further push the design possibility. It is a way to explore the expression of curvatures. On the other hand, the strips and fold method can also be used as strategies to form or assemble a complex geometry or surface. For example. In the Loop_3 project, the rationality of the complex geometry can be understood and studied by construct them using relatively more simple strip geometry. In Loop_3 project, the complex geometry are derived from planar strips elements.

B2 Case Study 1.0 Seroussi Pavilion
Introduction Continuing with the Strips and Folding, I also to explore the idea of indeterminacy in architecture structure and form. This idea have a strong emphasis on the vagueness of the structure and form. It make the formative and generative fabric become possible. The Seroussi Pavilion, is a project developed by Biothing and organized by art collector Nathalie Seroussi. It is a ground pavilion project located in Meudon, near Paris. The design of this project is inspired by the Sculptures habitacles on site, the main concept of this pavilion is an idea of maze to be integrate in the pavilion structure to achieve the purpose of organizing the spatial pattern and fabric. I think the reason that I am interesting in this project is the complex indeterminacy applied in this pavilion. The computational design method allow designer to create this complexity in its various facets and the pattern can be self-modified with the programming and achieve the indeterminacy. This project is a good example of idea of generation in computational design.

Methodology The programming of this pavilion is mainly based on the behaviors of electro-magnetic fields. They firstly made arrange field and computed the logic of attention and repulsion in plan view. Following the field logic constructed in plan view, sections of each micro arches are lifted by programming and at same time they are given different frequencies to create the complexity and diversity of the pattern. From the original center point, each branch curve are capable of extending and growing further differently on the basis of variable field condition. The site condition create the parametric information to direct each curve to adjust its
direction of growing. At the end, the interesting structure is formed and constructed by those intricate line work. The programming method of electro-magnetic field attracts me the most in this project because it give me a new perspective in the study of computational design. This logic of attention and repulsion again make me relies the potential of computational design. This method allow the patterns of structure become self-modified and create greater possibility of the form and structure. The volume of the pavilion is mainly defined by the curves formed by field attraction and repulsion forces, therefore it create a sense of separation but at the same time, it is coherence of this structure is also displayed clearly.

ICD/ITKE RESEARCH PAVILION 2010 The most important concept involved in this ICD Pavilion 2010 is [Material Behavior Computes Form]. In the physical world, the form and shape and the internal and external force is also considered interconnected. The physical form and the force is always interacting with each other and influence the way they perform. However, in the virtual design, the generation of the form and the force involved in the structure are also treated as two separated things. However, this pavilion provide a good example and give people insight on how the generation of form or geometry is related to the force applied and how this idea is applied and achieved by computational design method. By using the computational design method, the architectural form, material property and structural performance is considered and designed in this project.
FORM GENERATION AND MATERIAL BEHAVIOUR For this pavilion, it is built on the basis of the most common and material behavior, which is elastic bending. The material of strip is birch plywood strips and they are all robotically manufactured planar element and subsequently connected to each other in order to allow the elastic bent and tensioned areas to alternate along the length of strips. Furthermore, for the purpose of avoiding the concentrated bending moment at a single connection point. The connection points between neighboring strips adapted to changes along the strips. Therefore, 80 different strips of patterns are resulted due to requirement of changing connection points and they are finally more than 500 geometrically unique parts used to construct the structure. By using the bending, the force is stored in the bent region in each strips, which holds the structure into shape and increase the stiffness and structural stability at the same time.
The process of the design and construction of this pavilion is also a good reflection on how the computational method help designer to achieve the innovative result and allow more design possibility. From the initial stage of the design, the prototype pavilion is designed with computational design tool, where relevant material behaviors data are integrated as parametric information based on both physical and computational test.

B4 Technique: Development Reverse Engineer Step by Step
The three initial curves are used to define the shape pavilion and create the volume.
Move the cuve to opposite sides.
Divide each curve and connect point to curve in each branch.
Loft the curve to form the strips of pavilion.
Use this planar surface to solve the intersect between the curve and this surface to make sure the strips are all planar.
To evaluate each curve and gain more control in each curve to make sure the strips can have more flexibility.

B5 Technique: Prototype

Bending
This is an imitation of the joint used in the ICD Pavilion 2010. I basically built a cut section of the 3 strips to study how the joint can be used to hold them into shape, with one applied with bending force while two stay planar, I think this joint can be very useful for a bending structural because the joint between neighboring strips works very well in holding the strips under bending and constraining the movement.
29
Detailing
This joint is designed and 3D printed to connect the neighboring strips and also, the arched nots can fit the strips very well in the prototype, and I designed three notches with different angles which can be used in different connections. The problem is would this joint work in the real scale project, where larger pieces of strips and larger bending force may be encountered. Issues of material and other possibilities need to be further explored and considered.
In this prototype, the bending test is not very successful because most of the strips I used are deflected and failed to achieve the active bending. I am still looking for a more suitable material to achieve the active bending.
This is a base I designed to allow the strip to sit on, and I think it successfully allow the strips to stand very well, and it is very stable. The joint can be assembled from two parts which adds more adaptability to this joint.

B6 Technique: Design Proposal Fishway
Fishway I would like to design a structure basically located in the spot of existing Dights Fall Fishway. The Dights Fall is located in the junction of Yarra River and Merri Creek. The Yarra River is supporting 17 species of native fish and 11 of them need to migrate between salt water to fresh water environment. For this kind of migration, the fall has been considered as a major barrier for fishes. A fish way, is a structure designed to facilitate diadromous fishes’ natural migration. And after looking at the fishway example, I realize I can add more design feature into this interesting structure. And make this structure to be more noticeable that make people to admire the structure and at the same time thinking the natural eco system. My goal is making people to have a thought at the natural fish migration and by doing this to achieve the interaction and communication between human and nature.
The View from the Spot
In order to achieve the goal, I would like to get people involved in the Fishway but in a way not disturbing this natural migration. I would want integrate a viewing platform and pavilion above the underwater fishway structure. And the underwater structure should be visible by people by making the platform transparent so that people are able to take look at the undder water structure while they are in the pavilion.

B7 Learning Objectives and Outcomes
In the study of part B, as I get more familiar with using Grasshopper, I feel the design po the design process, however, the computational design tool not only visualize the design sign possibility. This the part that attract me most and push me further in the learning o because it taught me a way on how to find the solution in a design and solve the difficult would be the difficulties in a design and how to solve them.Prototyping is way of testing t ideas need to be able to achieve in physical world. And I believe the process of doing pro process of making change and adaption of idea is essential.
ossibility can be enhanced. The program can always be a tool to help n idea of designers but also enhance the design by creating more deof computational design. I found Reverse Engineer part is very helpful ties. It taught me what is important in the design process, and what the idea in virtual world physically. It is very important to understand, ototype is very important. While tasting the idea, it is ok to fail, but the
