For the first time the world exhibition Expo 2017 takes place in Kazakhstan.
Themed as "Future Energy: Action for Global Sustainability", an exhibition of superlatives is being built on a 113 hectare large site. Large and small objects form a breath-taking ensemble of modern architecture.

A second pavilion (see Flower pavilion) is the “National Day Stage”. A stage roof with auditorium, which is located in the immediate vicinity of the focal point - the Kazakh pavilion "Nur Alem". The supporting structure consists of five semi-circular, polygonal curved trussed beams, in which the radius of the beams decreases from the centre towards the outside beam. The trussed beams are connected and stiffened by compression struts. As it is a temporary construction, the loads are removed by means of concrete blocks, which are laid as a foundation under the entire structure in a grid-like manner. The stage area is divided into an outer and an inner stage area. The exterior measures 17mx22.5m, with a maximum height of 10.5m.
The inner, smaller stage area measures approx. 10mx15m. Thus allows the artists, property-masters, organizers, etc. to separate into areas "before" and "behind the scenes". The upstream auditorium provides protection for the viewer. The roof skins of all three areas are made of a PVC-coated polyester fabric. In the stage area, the membrane is placed transversely over the beams and fixed linearly to the edge beams. In the area of the auditorium, the membrane is also attached linearly to the main support of the stage area and anchored to the outside by edge cables and anchoring columns on the grid.
