The effect of discrete reinforcement on spindle‐shaped Tensairity beam

Tensairity is a lightweight structural concept, a synergistic combination of an air-beam, cables andstruts, which is categorized as a pneumatic structure. The central idea of Tensairity is to use low pressure of the internal air to stabilize compression elements against buckling. The basic element consists of a simple air-beam (a low pressure inflated tube), a compression element tightly connected to the air-beam and tension cables having a spiral shape around the tube.Optimising the air-beam designs is one of the interesting topics of Tensairity technology.
