Buitink Technology performed the engineering, production and assembly of 2 coverings for a private house in Voorschoten (Holland). The largest canopy covers a terrace of the house, the smaller one the entrance.

The membrane is tensed between the wall and a beam construction. Rolled profiles are placed between the wall and the beams to support the cloth.

Project data

Material:	702S van Serge Ferrari

Engineering canopies

3D model: large canopy covering a terras

3D model: smaller canopy covering the entrance (wave shaped)

Force calculations

Reaction forces are calculated for the larger covering. The simulation model first calculates the default weight and tension of the cloth. Subsequently various forces are applied in the model:

• snowfall
• wind
• combined forces
