Canopy bus station Leidsche Rijn Centre
Buitink Technology did the engineering, fabrication and erection of tensed membranes for a bus terminal in "Leidsche Rijn Centrum" in the Netherlands. The canopy consists of a spatial steel structure of 10 hexagonal tensed so called low point sheets, in between and alongside extended with 18 triangular high point sheets. Additionally 9 high points were placed in the middle of the structure.
Construction and connections of the roof
The 9 so called high point sheets in the middle are supported by a floating pole, while the 9 high point sheets along the edges are supported de-centralized. The edges of the 28 membrane sheets are connected to the steel construction through fasteners. The low points are equipped with adjustable fasteners, receptacles for rain water and lighting. Membranes are made of TX30 material of Serge Ferrari, guaranteed for at least 25 years!

Analysis and strength calculations
A thorough analysis through strength and force calculations have been perfromed on the structure, such as weight, tension, wind and snow load etcetera.
