| Abstract | This paper provides a general overview of fabric forming and illustrates the immense potential of the construction techniques. The concepts of tension forming and its application to the design and construction of rectilinear and curvilinear wall forming, columns, slabs, beams, variable section precast beams, trusses panels and thin shell vaults will be discussed. The practical application of fabric forming allows for more complex shapes and structural configurations than previously possible. Replacing rigid formwork panels and casting forms with a flexible polyolefin textile membrane allows for the economical production of simple and sophisticated concrete members with increased structural efficiency and exceptional physical beauty. The permeable fabric membrane allows air bubbles and excess bleed water to move through the membrane wall, resulting in increased strength and durability of the concrete (typically +10% to +15%). The concept of the fabric membrane as a “skin” over the form skeleton can produce complicated details derived using simple techniques. Practical techniques of forming, bracing and placement, and a history of constructed work and practical field results will also be discussed. Field results are impressive. The fabric lends itself to a reduction in form supports, bracing, and simplified form tie methods. Casting results rival large-scale gang forms, steel column forms, and exceed the possibilities of other panel form systems, and are simpler to construct. Additionally, examples of rudimentary and simplified techniques applicable to developing countries will be demonstrated. Finally, methods will be presented for integrating fabric forming with composite wall technology to produce unique, thermally efficiently, and durable structures. Fabric formwork techniques can be designed to conform to precise structural requirements resulting in a significant reduction in materials used, such as funicular compression shells and vault structures, as well as variable section beams. This paper will illustrate the immense potential of fabric forming and demonstrate the possibilities for constructing high efficiency, engineered structures as well as beautiful and diverse architectural designs. |
