| description |
In this paper, steel-reinforced composite columns (SRCs) with IPE profiles, commonly used in Iran, have been investigated under lateral and axial loads. The variable parameters in this study are the amount of axial load eccentricity and changes in the ratio of the applied axial load to the lateral load. For this purpose, ABAQUS finite element software has been used. Based on the results, it was observed that as the percentage of eccentricity increased (load to lateral load ratio of 0.5), the buckling load of the composite column has decreased. By increasing the eccentricity from 0 % to 100 %, the buckling load reduction rate for the first mode of the column is equal to 3 % and the amount of critical load reduction in this condition is equal to 21 %. It was also observed that the buckling load of the composite column decreased as the percentage of eccentricity increased (load to lateral load ratio of 1), by increasing the eccentricity from 0% to 100 %, the buckling load reduction rate for the first mode of the column is equal to 4 % and the amount of critical load reduction in this condition is equal to 20 %.
