Prestressed structure, getting reaction force from additional air-container, is called as Air-prestressed structure in this report. The aim of this report is to investigate fundamental mechanical properties in the axial direction, such as elasticity and loading capacity, through the vertical loading test, of air-prestressed cylindrical structure. Three prototypes, having different size and specifications, are tested and the results are reported. It was found that the top point of some specimens suddenly displaced in the horizontal direction under vertical load. The loading capacity of the prototype is calculated by an analytical solution, and compared to experimental result.
