Fabric formed shell structures utilizing bending active frames and principal stress lines

Date2016 - ...
SupervisorsLars De Laet and Mark West

Historically, fabric formed structures have utilized a flexible membrane, supported by a temporary rigid frame, to receive a liquid-to-solid material (like concrete, GFRC, ice, etc.). Recently, bending active frame systems have been explored as a support for fabric formwork because of their ability to produce complex geometries that complement the complex geometries produced by fabric. Because the principal stresses that move through complex geometries are predictable and curvilinear in nature, bending active elements have the potential to follow these patterns in a more direct way, helping to link more closely construction geometry and structural performance. This research explores a building system that uses these principal stress patterns to guide the design and construction of a bending active framed fabric formed ice shell. The advantages of this system are in the use of force-flow to determine efficient structural geometry, greater material efficiency, and unique architectural expression.
