The object of this study is to experimentally investigate the structural behavior of circular tube column bases under axial loads and to ascertain the test results using elastic numerical analysis. A literature survey was conducted on the AISC design code and a few design formulae. Tests were axially conducted under compressive loads. The thickness of the base plate was the main parameter of the specimens. Nine base plate specimens were used, with thicknesses ranging from 9 millimeters to 35 millimeters. The relationship of the load and the vertical displacement of base plates and the relationship of the load and the strain of the base plates were tested. Ansys version 6.1 was used for the elastic numerical analysis, to ascertain the test results. he test results and the elastic numerical analysis results will be used to suggest design formulae for inelastic numerical analyses that will be conducted later on.
