- Possibilities by example
- Nadrukkelijker in het Nederlands “Textiele bekistingen” vandaar “Textielmallen” Matter of taste of course, but shape and material of the formwork determine how concrete expresses itself, not the concrete itself. Concrete connotations of the every man/woman lie in rectangular/angular/robust/crude geometries, not associated with a fluid material

- Cast-in-place Advantage: Light-weight of the formwork; savings on transport, material Project info: Casa Dent, is a 303 m2 (3,300 ft.) private villa on the island of Culebra, Puerto Rico, designed by Fu-Tung Cheng of Cheng Design with Robert Lawson structural engineer. The architectural design and formworks, and on-site construction of these columns was done by Mark West in 2001 on consultation with Cheng Design.
- Prefabricated on site and cast-in-place (columns consist of 4 elements) Advantage: freeform design (double curvature) CAST and the Catholic University of Valparaiso are engaged in a long-term collaboration to design and construct experimental fabric-formed concrete architecture at the Open City in Ritoque Chile. As a part of the extraordinary experimental architecture of the Open City, this research and construction collaboration embraces both the poetic and technical dimensions of architecture.

- The design considerations for these formworks is similar to those in the design and engineering of tensioned membrane structures, involving the interaction of prestress, non-linear material behavior and the support conditions. Additionally, fabric formwork has concrete pressures and fluid structure interaction as complicating factors. There are two aspects that distinguish the design of fabric formwork from that of membrane structures, caused by its short term use. Firstly, the formwork invites the designer to apply not only fixed, but also supports along which the fabric may slide during stressing and casting, normally leading to long-term wear and tear. Secondly, the stress distribution within the fabric may be highly uneven.
- Ofcourse, West’s comment does not account for ultimate strength. (You would be hard pressed to make a fabric formed skyscraper in a single pour.)

- Current BESO models use very small loads and fictitious, isotropic, linear material properties BESO is fast, robust and straightforward, but inflexible , difficult to adapt Non-linear BESO results are indicative of optimal shapes, more realistic, but still not practical General optimization algorithm needed, as well as a manufacturing technique with potential for optimization Fabric formwork is relatively form free Current beam prototypes demonstrate the viability of creating complex geometries

- Fabric formwork constitutes a new way of constructing and therefore imagining concrete structures. The use of fabric as the main material for a concrete mold allows complex geometric shapes with the potential for re-envisioned concrete esthetics, structural and material optimization, cost savings associated with manufacturing and transportation as well as high quality surface finishes. The aim of this research is to investigate the complex interaction of fabric and fresh concrete, to study the consequences for rebar design, to develop computational tools for the design of fabric formed systems and validate the results. Parallel to these objectives, the value of fabric formwork will be investigated to identify threats to and determine key factors in the market development of this technology. The results of this analysis will frame and direct the development of the computational and experimental research.
