A wind tunnel experiment was led in Tong Ji University. The station has to support strong winds (up to 250 kg/m2) and resist to earthquakes but is free to expand because of temperature variations (+/- 3 cm at the end of the roof).
The cast pieces on the top of the columns include a spring for this purpose. The wind bracing follows the bicycle wheel pattern. And an undertension system stabilises the roof against rocking.
The main purlin include a tension belt (150 mm diameter full bar), able to support 300 tons tension, while the central ring supports 1000 Tons in compression.
The sunshade layer has been designed an optimised to minimise the sun penetration in summer at 12 am. and maximise it for the morning in winter.
