Photographer's Note

I liked the view of Khan Shatyr from outside, specially in the evening, but I was really fascinated with the structure inside. Here the view of the huge tripod.

The tubular-steel tripod structure supports a suspended net of steel radial and circumferential cables, which is clad with a three-layer ETFE envelope, formed as 3.5 x 30-metre cushions - a very light, economical and thermally efficient solution. The translucent material allows daylight to wash the interiors while sheltering them from weather extremes.
The roof cables are collected 90m above ground on a ring at the top of the steel tripod and span to the sloped concrete perimeter which forms the base of the building. Four intersecting arcs define the 140m long, 120m wide plan of the roof.Radial cables span from the top ring of the steel compression mast to the outer concrete perimeter and are prestressed against hoop cables to form an anticlastic surface. 192 pairs of 38mm diameter radial cables vary in length from 125m at the front of the tent to 70m at the back. The hoop cables are arranged perpendicular to the ridge line of the radials. he tripod provides the single point of support to the centre of the cable net and is an important element for the architecture of the building. Traditionally the central support of a conic tent is a single mast, pinned at both the top and the bottom and stabilised by the tent that it supports. The greatest challenge to overcome in the construction process was the erection of the the whole 1,700 ton tripod.
