Structural Membranes 2011 aims to be a forum for discussing recent progress and identifying future research directions in the field of textile composites and inflatable structures.The Invited Session ‘Membrane Mould’ will be organised by ir. A. Pronk (University of Technology, Eindhoven, The Netherlands) member of ISOFF. Persons willing to join an Invited Session or willing to give a lecture about a specific topic are kindly requested to send their abstracts to the conference secretariat. You can register at following website:
International Society of Fabric Forming (ISOFF)
The Society’s focus is:
- Improving communication between all participants: researchers, architects, manufacturers, distributors and concrete contractors;
- Communicating to the world the commanding environmental benefits of fabric forming over rigid formwork;
- Developing new and innovative fabric forming solutions.
This one – these designs provide a duel membrane that is cooler in the summer and warmer in the winter because of the space in between filled with circulating air or fluids – very, very nifty. Could be used in Haiti – but it would have to be modified because of the flooding that can happen there – would be more likely to be sustainable in hurricane winds because there isn’t a flat face surface to take the force of the wind in a brunt attack.

A look at how a school in Connecticut is not only teaching about solar power, but living it by reducing energy.
This is the company mentioned in the video from CNN about the CT solar school – (that is fully self-sustaining for energy needs and was put up in 7 months, that’s what could be done in Haiti and so many other places – but the structure has possibilities – house on the farm, place on the beach – business / retail buildings – very nifty.)
Shells are natural, logical and functional load carrying systems. If a space has to be surrounded by a minimal area of surface, the shell is the logical optimum. Additionally, for the load transfer of a uniformly distributed load, the shell structure is the perfect choice because mainly normal forces appear in the cross section1.
Although shell structures possess this excellent load carrying system and make a great visual impact, only few shells have been built in the last decades. The main problem is the difficult, time-consuming and expensive production. Traditionally, shells are produced by means of complex formwork. Creating such formwork increases the construction time and affords additional material which cannot be reused after the shell has been completed.
In order to achieve a more economic production of shell structures many new production methods have been developed. Beside the possibility of using formwork structures for more than one concrete step2 or using precast concrete elements, pneumatic formworks can be used. Frei Otto describes different applications of pneumatic formworks (air-houses) in his work3. One possibility to build thin concrete shells is to spray-coat an inflated rubber-like membrane with a layer of concrete. Another procedure consists in inflating a membrane covered with freshly mixed concrete.
According another construction method4,5 it is possible to build a doubly curved shell from a flat circular plate made of concrete and a soft styrofoam component between segments which enables the plate to be deformed.
A tendon is placed along the edge of the plate. The erection becomes possible by stressing the tendon so that the circular plate slowly lifts up with the help of a pneumatic formwork to give the needed vertical impulse and outweigh the dead load. The photographs in Figure 1 demonstrate the shaping process
