Abstract

This paper focuses on the strength and behavior of rectangular hollow sections (RHSs) tapered columns subjected to uniform axial loads. Within this work, seven columns with different shapes and dimensions were tested under concentric loading. Numerical analysis using FEM Software ANSYS is performed on the tested models and the results are compared with the experimental results. After this verification of the FE model a parametric study was carried out. The column strengths predicted from the parametric study were compared with the design strengths calculated using the American (AISI-2001) and European (EN-1993) specifications.
