Aesthetics, Geometry and Structure in the Shells But this can Waller patented the system Ctesiphon in and in the late 70s the system had been used in over structures throughout the world. One of the examples is the Chivas distillery warehouse which has a height of about 30m and a span of m.
The thickness of the shell is impressively slender at only 6.
In , the Eindhoven University of Technology developed a set of experiments based on the screen concrete projection method, whereby they made a prototype measuring 7m high by 2.
The analysis of the implementation process revealed that the projection of concrete might change the shape of the surface . The University of Brussels built 10 prototypes with a span of 2m and 5cm thick, made from shotcrete tensioned on the screen. This variation was due to the sliding of the attachment points as well as the dynamic effect induced on the surface by the concrete projection.
Concrete additive latex Latex Polymer when added to mortars in the coating process provides sealing and elasticity to the surface. The "Roof Nez" how it is affectionately called, owes its name to its designer George Nez.
This coverage is characterized by low production costs and a remarkable resistance and waterproofness. It is constructed by applying concrete added with latex on a screen support. Despite its simplicity, this process is highly effective.
Tests conducted by the bureau of parks in the United States, in Knott Laboratory in Denver, show that this coverage has a high performance compared with normal covers, resisting four times more to cold and heat. Although the cover is 1 cm thick, it is sufficiently strong to support the weight of a truck on it.
Billington - Thin Shell Concrete Structures
The process consists of fixing a screen on the support elements of which the core consists of fibreglass and then poured concrete composed of sand, cement, water and latex. The vast work attributed to his professional practice comes from unifying the design and construction phases, resulting in the development of a set of construction techniques.
His vast knowledge of the hyperbolic parabolic geometry allowed him to design a formwork system based on conjugated linear elements with part wedges. Pre-stressed masonry Eladio Dieste developed a set of technical and structural morphologies thanks to an interdisciplinary approach that embraces the structures, materials and architecture.
His work is based on the relationship of structure and form and his architecture is a synthesis between form finding, structural behaviour and spatial qualities. He believes in shape as a medium to obtain structural resistance, so by geometry manipulation he moulds the structure so as to obtain structural efficiency, and gives significance to the architectural space.
For David Billington the work of Eladio Dieste is "structural art" combining efficiency and structural expressivity . Diest has a strong link to the construction process, which in many cases is the origin of his innovations.
His constructive concept was largely due to a systematic refusal to incorporate technology coming from the "developed world". He tried to solve problems bearing in mind the circumstances and their environment .

To contrast with European designers, he avoids the use of concrete, choosing brick as his construction method. This option was based on an indigenous and ancestral tradition in Uruguay. He used the curved surface of vaults to resist buckling and to improve the structural efficiency and focused his research on pre-stressed masonry.
His construction technique was based on low-tech solutions, to pre-stress his structural shapes he overlapped steel loops firmly anchored to the vaults, and then with a car jack introduced stress to the surface. Discrete flexible formwork This process has several variations, but basically this system replaces the membrane of flexible formwork for insulating material tiles, which are linked with cables. Geometry of buildings was resold to a panel of four hypermarkets.
This shell had two layers of 3. The bottom wires were spaced 30 cm apart and the top layer 60 cm apart. The shell used a 3-inch thick EPS foam, a 0. The work developed tries to prove that it is possible to reduce the amount of material used in the construction process, especially in the falsework, by introducing a flexible formwork.
To do that, the shuttering is replaced by a fabric and the falsework by a cable net, supported by an external frame at its boundaries . The challenge is then to design the flexible formwork so that the resulting shape matches the designed geometry. This approach proves to be very innovative, able to solve the main production problems of the doubly curvature geometry.
However, the flexible formwork made of brick proves to be inaccurate, causing deformations on the surface that could be aesthetically displeasing to the appearance of some surfaces.
Standard vaults In , Serguei Bagrianski, a student at Princeton University, developed a standard vault as part of his master's thesis. He believes in the potentiality of the double curvature. For him the answer to build this structural shape is standardization, so he built a prototype to a large scale, made with ultra-high-performance fibre reinforced with concrete.
To produce its modular pieces, he divides the vault surface into triangles. With these modules he can replicate this shape easily, minimize the construction time and reduce labour costs. Support frame The construction process is based on a reusable and prefabricated frame. This element is made up of two pairs of telescopic bars, stabilized by a telescopic truss.
These articulated joints form the frame and allow to stabilize and manage the size and curvature of the surface. This support has a set of predefined attachment points for the cables, which form the cable net that defines the surface. Oricrete formwork The formwork and its requirements are decisive for the final cost of the construction, as well as the final expression of the built form.

The present research takes advantage of the experiments previously made with flexible formwork associated with cable net. This process proves to be very effective because it does not need falsework; however it is very susceptible to deformations.In the s, Anton Tedesko first introduced reinforced concrete thin shells in the United States.
Context The earlier reflection suggests that one of the decisive factors in the production of Shell concrete is the formwork system used. The metal folded sheets work as the formwork.
This principle is used in many areas of engineering construction. The spectacular simplification Cylindrical Shells.
