More about the structure
u Different forces:
u Fabric is held in tension only
u It is stretched over steel arches that are in compression
u Cables hold the fabric in tension
u Scalloped edges allow movement of membrane
u Prevents over stressing of the fabric and steel
-
Different types of tensile structures
-
Olympia Park Munchen, Frei Otto
Resembles a kite or paraglider
Other tensile structures
Canada Place (BC), Expo 86…Tensile structure resembles the sails of a boat
-
Our model and process
u Our materials:
u Flexible fabric
u Carbon tubes (kite shop)
u Chip board
u Thread (lots of it)
u Tooth picks
-
Our model and process
u Side and front elevations for approximate dimensions
-
Our model and process
u Autocad: visualize where arches are and how they work
-
Our model and process
u Structure, arches, thread, fabric (sewing, lots of sewing…)
