Abstract :

Tensairity is a new light weight structural concept. The key principle of Tensairity is to use low pressure air to stabilize compression elements against buckling. The basic Tensairity structure is a beam with the properties of a simple air beam as light weight, fast set up and compact storage volume but with the load be� capacity of conventional steel girders. Ideal applications of the Tensairity Technology include wide span roof structures, temporary buildings and footidges. An experimental investigation had been carried out to understand the behavior of a Tensairity beam subjected to concentrated load in comparison with that of a RCC beam to determine its ultimate load carrying capacity and deflections. The Tensairity beam has been casted with a flex of 1m length and 30cm diameter is made into a cylindrical memane filled with compressed air with an internal pressure of 954N/mm2 making it a very light and deployable beam
