The term “biomimicry” was proposed in the 1980s by the biologist Janine Benyus, author of the book Innovation Inspired by Nature. The term referred to the study of the functions and structures of biological systems as reference models for design in the field of engineering. Steel, at a conference entitled “Bionics Symposium: Living Prototypes, the Key to New Technology”. In 1960, the term “bionics” (as a combination of the terms “biology” and “technics”) was also invented in the USA by Jack E. Schmitt to designate a new field of knowledge within biomedical engineering. Specifically, the term “biomimetics” was proposed in the 1950s by the biophysicist and engineer Otto H. However, the formal creation of the field of knowledge in biomimetics is very recent. Countless analogies can be found in the architecture of all ages.

Through the calculation models developed, it has been possible to verify the poor performance of the initial designs compared to the power of the final solution, which, after more than 5 years of research by the design team headed by Utzon, was able to solve the enormous problem with a “simple” typological and geometric change. This paper analyzes the influence of nature as a source of inspiration in this World Heritage building, assessing through FEM calculation models the suitability of the different solutions proposed and weighing up the influence of certain factors such as scale in this type of process. This is the case of Jørn Utzon and the design of roof shells of the Sydney Opera House, in which the search for natural references was constant, from the nautical references in the initial design phases to the final spherical solution based on the analogy with an orange. This site was added to the UNESCO World Heritage Tentative List on Novemin the Cultural category.Architects throughout the ages have looked to nature for answers to complex questions about the most appropriate structural forms for their buildings. The three domes of the plant were built at the same time and to save costs Candela appealed hyperbolic parabolic form as it allows the use of a straight formwork.Īlthough tensions in the shells are small and the steel reinforcement was not necessary, it was used for constructive reasons, to hold wet concrete in place on steep surfaces and to address other practical issues such as the effects of temperature changes. Similarly, the frames of the reinforcing ribs of the skylights are fixed to the arches that surround them. The arches are located directly on the glass walls to ensure that in case of unexpected wind loads of the shell is sufficiently rigid as to not allow the movement of the crystals. Additionally placed reinforcements on the edges which allows the thickness of the shell is expressed fully. Steel loops to connect the foundation can withstand the horizontal forces, these braces are completely hidden from view.Ĭandela used V-beam in all its vaults.

Four skylights fill the gaps between adjacent tanks and end of squaring the structure but do not provide sufficient support for the shell of roofs.īacardi shells are not in direct contact with the foundation, each of the four corners is supported by a leg that transfers the loads from the vaults to the foundation, which in turn download the weight vertically on the ground.

The original cover of the bottler was composed of three vaults hypars, adjacent edges of 4 cm thick and 2.50 m roof blown from the sides. Originally constructed between 19, Felix Candela and Ludwig Mies Van Der Rohe designed the corporate office building, bottling plant and ageing cellars of Bacardi & Co.
