dc.description.abstract | The paper presents the experimental testing of the axial capacity and stability of short,
moderately slender and slender circular CFT columns. For the purpose of sample testing a special
set of hydraulic presses was constructed. In order to achieve centric loading of the load, a device
calotte was used. With the help of the dosing and gauges placed at the top of the column, force
and vertical displacement were measured continuously. The test was carried out on two short
columns 0.5 m and 1.0 m long, and four moderately slender and slender columns with a length of
4.0 m with different boundary support conditions. In the short CFT columns the confinement
effect was taken into account as well and loss of bearing capacity occurred due to the steel profile
yield strength. In moderately slender and slender columns, the loss of stability occurs before the
loss of the load capacity of the column. The obtained results of the experimental tests were then
compared with the valid regulations: EC4, ACI, AS and AISC. It can be concluded that EC4
gives the most approximate results to the experiment. | sr |
