Regina Stack – concept

There are 3 main sources of circulation around and over the site. 2 bridges and 1 street. 2 vehicular and 1 pedestrian. A box is placed around all curculation paths to isolate them and pull them away from the site itself. This is to try to help with noise level and privacy of the site.

The boxes surrounding the bridges were then pulled upward and the street level box was pulled down from them. I then experimented with ways to enclose a space from them and came to the concept of wrapping a ribbon like shape over the bridges and down onto the site and up from the street and over the site. This wrapping of ribbon created interesections. From these intersections, pinpoints were placed. Then, these pinpoints were raised or lowered based on location. Ones closer to the bridge were lowered to giveĀ separationĀ and the ones toward the center were raised to create a space inside.

These pinpoints and ribbons can be manipulated much like the cats cradle method where the ribbons intersect in different patterns and these patterns create pinpoints which can be raised and lowered to create a unique space.

P1_Regina Stack_Pneumatic Structures

Pneumatic Structures:

A pneumatic structure is essentially a structure where air is the main support. This is achieved through the use of a flexible material which is pressurized and inflated. The use of pneumatic structures began when a Brazilian priest conducted experiments with hot air balloons in the early 1700’s. This first balloon was constructed out of linen and paper and was 11m in diameter. This technology was experimented with and used to advance the hot air balloon and then transitioned into architecture in 1918. An English engineer, F. W. Lanchester, was the first to utilize this type of pneumatic system in a building design. However, because of the amount of appropriate material needed and lack of such material the project was never completed.

After the invention of nylon and during the second World War, the military started utilizing this type of technology. Pneumatic structures were constructed for emergency shelters and decoys. This led to the construction of structures that would not interfere with radar signals and the development of a thin non-metallic structures. These “radomes” also helped the company constructing them to develop other types of uses for pneumatic covers (covers for warehouses, swimming pools, sports facilities, and factories). However, using this technology for large scale buildings can be very complicated. The amount of air used to keep the structure pressurized correctly and what type of secondary structure to utilize are some factors to consider when using a pneumatic structure. For instance, the Minnesota Metrodome, which was constructed to protect the Minneapolis stadium from snow and weather, deflated due to snow accumulation. A large, flexible material was essential stretched over the exposed stadium and the building was pressurized. This material was reinforced with cables running vertically and horizontally across the structure and snow accumulated where the cables and material met. One of the main factors for the structure to be constructed in the first place was the main reason for it’s collapse. With the advancement in this technology, however, these problems have been explored and solutions have been established. To prevent this type of collapse from happening again, for example, cables can be positioned closer together to reduce the amount of snow that can gather, using higher internal pressures, and using higher profiles.

While this type of system has been used for large buildings such as stadiums and factories, the use of pneumatic construction in multistory buildings may be possible.

Fire protection, construction techniques, pressurization and air-conditioning equipment, general safety, etc are some of the main topics covered in the article. If this is a type of construction method you are looking into for the hotel project, I highly recommend reading more into this article as it covers more in depth the way to make a multistory building with a pneumatic structure.
