PRELIMINARY EXPERIMENTAL RESEARCH OF AXIAL MECHANICAL PROPERTY AND STABILITY OF TENSION COLUMN PRESTRESSED BY AIR TUBE

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