“…Similar observations have been reported for CHS in bending in previous studies [30,31]. The beams ultimately failed by inelastic local buckling of the compression (upper) portion of the sections in the region of maximum moment near the point of loading (See Fig.…”

“…This configuration creates a constant [12], Sherman and Glass [13] and Jiao and Zhao [14] utilized this arrangement for testing on circular hollow sections (CHS), whilst Korol and Hudoba [12], Hasan and Hancock [15], Zhao and Hancock [16] and Wilkinson and Hancock [17] adopted this setup for testing on square and rectangular hollow sections (SHS and RHS). They utilized the test results and the derived moment-curvature relationships for the establishment of design rules.…”

The recent emergence of hot-rolled elliptical hollow sections (EHS) within the construction industry has attracted considerable interest from structural engineers and architects. Comprehensive structural design rules are now required to facilitate their wider application. This paper focuses on the bending strength of hot-rolled elliptical hollow sections; the results of detailed experimental and numerical studies are presented and structural design rules for EHS in bending about the major and minor axes are proposed. A total of 18 in-plane bending tests in three-point and fourpoint configurations have been performed. All tested specimens had an aspect ratio of two. Full moment-rotation and moment-curvature histories were derived, including into the post-ultimate range. The experimental results were replicated by means of non-linear numerical modelling. Following careful validation of the models, parametric studies were performed to assess the structural response of EHS over a wider range of aspect ratios (between one (CHS) and three) and cross-section slendernesses. For design, cross-section slenderness parameters have been proposed and a set of classification limits in harmony with those given in Eurocode 3 for circular hollow sections (CHS) has been derived. A new Class 3 limit has also been proposed for both EHS and CHS. An interim effective section modulus formula for Class 4 (slender) elliptical hollow sections based on BS 5950-1 has also been developed. Further investigation into effective section modulus formulations is currently underway.

“…Jiao and Zhao (2004) tested the bending behavior of very high strength (VHS) circular steel tubes, and proposed their plastic slenderness limit. Lee et al (2001) studied the influence of diameter-to-thickness ratio (D o /t ratio) on the response and stability of circular tubes subjected to cyclic bending.…”
