VORONOI
Voronoi Arithmetic are used in traffic route calculating, pixel processing, even mesh subdivision, the output of several points is so abundant, and this project tries to use voronoi in three dimention with simple control points to generate an underground space in a courtyard. An attempt to use voronoi in an architecture project. 2019

3D view of the underground space 12 control points in total, which create 10 cell spaces and 89 pieces of wall or staircases. Enjoy the feeling that can only use the point to create architectural elements, and the position and angle of all the walls and seems random, but they make sense. I believe when you stand inside each cell room, you will feel the control point of the room even if it’s not indicated physically.

SHELL HOUSING
Single unit house in campus design, site area 23*12 feets, provide a resident space for one visitor professor to live, including shower space and an easy kitchen. The interesting part of this housing design is on the ground level different functions are separate from each other, but in the top-level, all the space gathers together and forms a circle. 2019

INVERT
The cure on Eiffel Tower is formed by wind load, when the wind came from left, the right part tension, when the wind came from right, the left part tension. If I invert the whole structure, and everything is in a mood of tensile. Use rope to replace the member of the iron, and get a space is form by tensile force.

Rope for tension
One leg table Later in a one-day charrette, change the system into a one-leg reliable coffee table, all the gravity above transform from a wooden stick in the middle, all the rope cable are in the condition of being pulled tight which make the system stable. In this way, arouse the potentials of the compressive strength of the stick.

FAKE ARCH
Real arch need vertical force to balance, remove this force, the arch become a shell. Like the eggshell, the outside shell resist pressure and the inside membrane resist pressure, even when the eggshell slightly broken, the ‘arch‘ still stand. Although its not as beautiful as real arch in stress, but it can form something that is full of misunderstanding and order. A design from material and static 2018

Plaster Carbon Paper
Plaster good at resist pressure, but it’s super crisp. Carbon paper can form shape when put tensile force.

Pu t a p i e c e o f c a r b o n p a p e r o n t o curve-model, wet it out. Spoon the plaster on to it, about 1-2 mm thick. After plaster becomes stiff and the carbon paper dry, it shrink and form a pre-stressing force to the plaster.

culation diagram for static structure
A geometry can be static in three-dimensional space, it needs to follow some principle : From at least two direction, it can always be simplified as a statically indeterminated structure. Follow this principle, using stub and rope to add or detach its degree of freedom.
For its fake arch, only two supporting points of the final model are fixed pin point, other connections are hung into the space, which crate misunderstanding to the arch-like curve.

UNIFORM STADIUM
Use sensors to get information from a real architecture environment, use it to trigger some simple physical movement to improve the building environment. Inspiration is from watching the soccer match, most time sunlight cannot cover the whole filed, sometimes half of the field is overexposure or underexposure on TV broadcasts, also, people have experienced feeling cold or stuffiness in a large stadium without AC. This design wants to use a simple uniform operable aperture to regulating climate in a ring stadium, the outside uniform aperture both control sunlight and ventilation.

STRUCTURE WORK
A competition using wood to simulate a three storey building. Put 159kN gravity above the wood model, see how it performed under an intense horizontal force. The quality of the structure depends on the horizontal acceleration at the top level, the weight of the wood model and degree of damage. The material property of wood sticks is unstable, which means we cannot calculate the stress and strain precisely, we can only use the result of experiment, left shows we use slow camera to find out the weakness part of the structure and strengthen that part.. The result is good, its safety, and we can see large deformation which means the structure is soft but resilient.

The sound wave represent some damage inside the model, the structure use the damage to consume energy but you can not see it.
In this experiment, after several time of cnosume energy, the structure can not resist anymore, collapse.

KANGROO WORK
Pull a mesh into a 3D-curved mesh, the pull point becomes the supporting point for the structure. Apply different radius pipes to each edge of the mesh, depending on the changed length of each edge. How the stress transforms from top to above. At first all the mesh edges are in the same length, after giving the force, they are extended into different lengths. Pull the Mesh
Start using Kangaroo again in GH recently, expect physical simulation, wondering what it can help with form finding for engineering also more complex shape to architect, really interested in the basic principle of how Kangaroo jumped.

STRUCTURE INTERN WORK
Interned in a structural department in East China Architectural Design Co., where I worked on proposing reasonable and practicable structural options to architects. Most works are space structures, special structures with different materials. It is not only about stress analysis but also about form-finding, mesh subdivide, deep material discussion.

Shanghai Juss International Equestrian Center A large zigzag-curve-shape roof, supported by several concrete cores underneath, using steel truss to span. Cause the shape is to complex and architects changing the shape all the time, use GH to generate the shape of each truss, in this way we can reflect the architects really quickly.

A Sphere Structure A high-rise building in Xi’an city, on the top floor, the architect is asked to build a sphere on the top several floors, like a Chinese lantern, which is the symbol of the city. Except subdivide the sphere into mesh line as fuller did, also proposing a tension system since we can easily find someplace to hold the tension of steel cable. In the diagram, red parts are steel circular ring, blue parts are steel cable, all she system are in the state of tension. Conceptual design Level 2019
Curtain Wall Design Research on glass curtain wall design, transparency, and rhythm of curtain wall always depend on the size of the members. Write a small grasshopper file, with the help of Karamba, to help architects decide what kind of system curtains, space between each member. Input different edge conditions, wind environment, chinese code, frame or post-tension cable. Optimized member size. Grasshopper file 2019

A one-week Olympic Village Charrette design with a 6-hour torch installation design for 2028 Summer Olympics. Our design proposed an Olympic Village in the shape of five interlocked rings resembling the Olympic flag. Composed of cells representing rooms of different types, which could be chosen by athletes and then attached to the ring-shaped frame, this customizable Olympic Village was designed to house athletes during the Olympic Games and to be disassembled afterward. The individual cells would then serve as shelters for the homeless, and the empty rings as a city park.
For the torch installation, start with a basic tensegrity structure unit, use curved sticks to replace the normal sticks, which echo the curve of the structure underneath. Group with MG, JW Ji 2019 The First Prize of Olympic Village Challenge For Eighth Annual Design Charrette USC, Awarded prizes of $15,000.
