Suspension Bridge by rope in Tibet

Individual Work (Nov. 2021)

Instructor: Yiqing Wang (email: wangyiqing4214@gmail.com)

The project is to reconsider the form of bridge in Tibet to meet the basic requirements and also their mental pursue. The site was originally an abandoned suspension bridge. During this project, the concept of Prayer Flages is used to construct bridges, it is suitable for the special geographical environment and religious atmosphere of Tibet through consideration of space shaping and ease of operation. Tibetan residents can participate in the construction of the bridge, and the religious memorial bridge through the clear form of force also makes this bridge worthy of construction. When Tibetans walk on this bridge, they could experience the same feeling as turning the prayer wheel and the wind blowing through the prayer flags. While this time their footsteps turned into language, they chanting by step.

Bridge Form/Case/Material Study

On the avenues leading to Lhasa in various places, the believers started from their remote hometowns, wearing protective gear, knee pads, and a fur coat hanging on the front. They kowtow every three steps along the road until Lhasa faces the Buddha. However, Tibet is known as the roof of the world. There are many rivers, mountains and mountains are eroded by flowing water, and there are thousands of ravines, which have made Tibet difficult since

ancient times. In the old days, local river crossings mainly relied on zip lines, cowhide boats and horse-head boats. In people's lives, the bridge not only bears the needs of daily life, but also facilitates the believers who travel to Lhasa on a pilgrimage.

Hanging prayer flags is a religious custom that has been circulating in Tibetan areas for thousands of years. It has the merits of self-cultivation and benefiting all living beings.

Every time the wind blows the prayer flags, it is like reciting the above scriptures once. The Buddhas of God protect all the people who make and hang prayer flags. Where there are prayer flags, there are good and auspicious. The five colors symbolize the five phenomena in nature, which are the material basis on which life depends.

[Village of Animal-shaped Houses]

A series of houses developed from Triple decker

Group Work (Dec. 2022)

Instructor: Ritchie Yao (ritchie@dashmarshall.com)

By creating a village of residences, artist studios, and retail spaces, stitched together by a series of outdoor “rooms,” this proposal for the bell hooks Creative Residency seeks to densify a wedgeshaped lot in Dorchester, MA. The complex of buildings forms a cast of characters – diverse types that can accommodate a range of uses throughout its lifetime – yet is grounded by a modest material palette that matches the surrounding neighborhood and establishes a sense of domesticity. Exteriorizing the vertical circulation maximizes interior flexibility, allowing the buildings to return to the community after the Creative Residency outgrows the site.

[Weave by Force]

Carbon Fiber weaving Pavilion

Team work by Li Yidi; Li Han; Qiu Shiyu

Instructor: Zhe Liang; Tim Lai

Contribution: Three members cooperate in every part and every participate from design to onfield construction

The project aims to explore more possibilities of carbon fiber materials in construction. In this experiment, three materials of carbon fiber, glass fiber and PVC were used, and two kinds of fibers were used to simulate the weaving of tensile stress and compressive stress, so as to realize the optimization of the force. The concept of bionics is used to evolve the logic of carbon fiber and glass fiber weaving under force, and the physical construction of the pavilion is realized based on this logic. After the construction process is completed, the pavilion can be independently supported without external support such as screws or supports. This also fully demonstrates the effectiveness of this form of force and the rationality of the triangular column design.

The generation of the shape structure mainly simulates the weaving behavior of weaver ants. The weaver ant curls and stitches the page. Therefore, in this design, the pvc board that simulates the leaf surface is curled, and the three pvc pages are stitched. After the shape of the three arches is determined, through the limitation of overall simplicity and beauty, as well as the optimization of the overall most effective force, the structural form of Figure 3 is finally

determined. In order to enable the three arches to stand independently under force without the need for foundation support, in Figure 4, the design adopts the mutual weaving form of triangular columns, and the joints of the three arches are connected and reinforced, so that the three arches can be The purpose of independent support.

The carbon fiber and glass fiber generation path of the pvc skin has undergone many revisions. One of carbon fiber and glass fiber expresses the tensile force in the actual force of the structure, and the other expresses the pressure. After pvc size is determined, the path of carbon fiber and glass fiber is analyzed through the grasshopper parametric analysis to simulate a certain amount of load. Through the gradual improvement of the load form and the artificial simplification of the force path, the result is finally obtained with simple structure and beautiful appearance.

Stratification of structure

The pavilion is mainly composed of five parts, from bottom to top in turn are:

1.wooden base fixing layer;

2.PVC mold layer

3.fiber bearing layer of glass fiber

4.fiber bearing of carbon fiber

divided into three layers according to the thickness, medium and thin of the carbon fibers according to the stress distribution

As the bottoming part under the carbon fiber, shows the stress line as the tensile part. In order to show a primer effect, the glass fibers are evenly distributed.

After completing the design, we first built a small schematic model to avoid various problems in the actual model building process. The light and shadow effect of the small model is better. However, a series of problems were encountered during the construction process, such as the difficulty of joining the

seals, and the problem of how the carbon fiber adheres to the surface of the pvc. Through the gradual design optimization, the construction schedule was finally obtained, and then the on-site construction was carried out accordingly.

Reinforce the three legs of the pavilion, the triangular column part is cyclically wound between the three legs, so that the three pieces of pages are connected to each other.

[Rolling a Section]

Form a building from two given sections

Individual Work (Oct. 2022)

Instructor: Ritchie Yao (ritchie@dashmarshall.com)

This project begins with two sections cut from several possible buildings. In film, in order to unfold an account with clarity, these seeming discontinuities cohere somewhere in the story into a disparate elements in order to clearly express an idea and to meet necessary functional requirements.The composition of the given sections may not be altered. No walls or other elements may be added to or subtracted from the given drawings. Drawn lines may be altered in their line weight and line type, and no lines may be deleted or added in the given drawings, with exceptions as noted below. All changes, subtractions or additions, must take place in front of or behind the two particular section cuts.

As a library with cafe, this building has four floors within it. First floor acts as lobby and snack shop. For second floor, there are individual reading rooms and book shelves. Third floor is the main floor of cafe and there are also more reading areas. For both second and third floor, two half sphere region are connected by large steps where people can get seats and talk. In forth floor, there are individual offices and dinning hall.

A form created by Repeated Units

Individual Work (Feb. 2023)

Instructor: Michelle Chang (mchang@gsd.harvard.edu)

Design and define the properties of a family of five architectural bays that can aggregate to form a range of enclosure, from fully enclosed to semi-porous, and that can provide 3-dimensional form to the established functional organizations. Suggest potential sites and climate situations for the aggregations. Speculate on changes to the bay and/or the aggregation that may make the aggregation more or less suited for a particular site or climate. Establish a pair of typical functional organizations that each provide three areas for performance. The aggregation must be formed ONLY through the aggregation of the Architectural Bays without additional partitions or structural supports.

Deforestation Warning Hall

Individual Work (Oct. 2021)

Instructor: Yiqing Wang (email: wangyiqing4214@gmail.com)

The project is to tell people about the serious consequences of forest degradation caused by mining in the forest. The site was originally an forest cover region in Peru, while nowdays espacially 2 years, deforestation in this region becomes quite serious. Whether it is the large-scale destruction of ancient rivers, excavation pits caused by heavy machinery and the destruction of surrounding forests, they have caused painful and even irreversible losses to the forest. The building is located at the edge of the forest degradation line. It faces the dilapidated land in the mining area and is backed by the lush tropical rain forest. The obvious difference in the landscape between the two ends of the building and the damaged land within reach are used to warn people of the natural cost of mining.
