1-4of May 2015 for the O'Gorod festival we ,"107" crew, have implemented our project named "Arches".

Facility description

Our facility is a TENSEGRITY construction ( from "tensed integrity"- connection by tension). The term "Tensegrity" was introduced by famous architect and engineer Richard Buckminster Fuller, whose ideas were developed subsequently by Kenneth Snelson and other researchers.
To creating "Arches" we were inspired by the works of Soviet artist Vyacheslav Koleichuk (in particular, by his design "Standing thread") ,and the University of Tokyo student projects ("Moom pavilion" and "Ninety nine failures pavilion").
We wanted to create a large-scale design which would organize space both within and outside itself (that's why we've chosen the location on one of the two parallel park alleys) and would represent a clear, elegant and robust constructional solution. Also we were keen on the idea of purchasing experience in making manually assembled object, which was elaborated using parametric design techniques (software Rhino+Grasshopper+Kangaroo).
Our arched vault is formed by nineteen parabolic arches. Each arch is made up of eleven rods, fastened with one stretched steel cable, and the shapes of the arches are designed parametrically : on the plan one of the generatrices of the vault has a curved shape, while the other is straight, and the height of each arch is in inverse proportion to its span (the more is span, the less is width ,and vice versa). In the longitudinal direction arches are fastened together with four cables running along the entire length of the vault and descending into the backstays . For the safety of Park visitors backstays were marked with colourful flags.
Wooden handles of the spades 1200 mm long, 30 mm in diameter and galvanized steel cable with a diameter of 2 mm were used for building arches. Arches rest on the wooden beam cross section 100x100 mm, mounted on columnar supports. The beam can also serve as a bench for visitors of the Park, as the distance between arches is enough for it (75 cm).
