| Abstract | This paper aims to numerically investigate the cross-section capacity of cold-formed steel elliptical hollow sections (EHS) with steel grades up to 960MPa. In the present study, a parametric study on the stub-column strength of cold-formed steel EHS was conducted for a wide range of steel grades and cross-section slenderness values by using a validated finite element (FE) model for the stub columns of cold-formed steel tubular sections. Based on the generated FE data and the collected test data; the existing equivalent diameter method, the traditional design rules for circular hollow sections with equivalent diameter incorporated, the Continuous Strength Method, and the Direct Strength Method, which have not yet been calibrated for cold-formed high strength steel EHS, were evaluated by comparing their predicted stub column strengths with the numerical and collected test data. The Continuous Strength Method and Direct Strength Method were found to provide better predictions than other design methods. Modified CSM base curves were then developed to further improve the accuracy of the existing CSM for cold-formed steel EHS with steel grades up to 960 MPa. |
