Experimental and analytical investigation of steel column bases

The present work is devoted to the experimental and analytical investigation of the steel column bases. Therefore, eight sets of tests, simulating the column to concrete foundation joint, were carried out. Beside, three-dimensional FEM models of the test specimens were constructed and analysed. Finally, the results of these experimental and FEM analyses were correlated with those obtained from an analytical formula proposed by the authors in a previous work, describing the relation among bending moment and angle of rotation (M–φM–φ) of the column base. The verification among the results seems to be satisfactory.

► The experimental and analytical investigation of the steel column bases was examined.
► Tests were carried out and the (M–φM–φ) curves were plotted.
► 3D FEM models of the test specimens were also constructed and analysed.
► The experimental and FEM results were correlated with the corresponding analytical formula.
► All the experimental measurements are presented in the attached appendices.
