Summary
[edit]
| Description |
English: Explanation of Tensairity girder as structural component. Comparison of (a) a normal steel framework girder and (b) a tensairity girder. When the load applies from the top directing downward (trying to bend the girder), force acts on upper rods of girders as compression stress yet as tension stress on lower parts. This stress tends to decrease girder width making it less rigid. (A girder of zero width has zero flexural strength.) To prevent this upper and lower rods must be separated. Classical framework girders ensure this using triangular space frames. In the tensairity girder strong airbags pressurized with a gas is used instead. The pure tension on the lower rod load may be replaced by rope or the strong airbag membrane itself. This results in a much better strength-to-weight ratio. |
