“…A brief review of the previous experimental and numerical studies of S690 high strength steel welded I-section structural members is provided herein. Rasmussen and Hancock [4] performed stub column tests on S690 welded Isections to investigate their local buckling responses and compression resistances, while the flexural buckling behaviour and strengths of S690 welded I-section long columns were experimentally and numerically studied in [5][6][7][8][9]. Ma et al [10,11] carried out a testing and numerical simulation programme to examine the global stability of S690 welded I-section beam-columns subject to combined compression and bending.…”

“…The lack of experimental verification of high strength steel structural members and joints at present limits the actual application of high strength steel in construction engineering. Experimental investigations have therefore been prompted to verify the structural behaviour of various types of high strength steel components (e.g., stub columns [1][2][3][4], long columns [5][6][7][8][9] and beam-columns [10]) of Ishaped sections, quantify their cross-section (or member) capacities, and develop precise design approaches. However, it is worth noting that research into S690 high strength steel welded I-section beams remains relatively scarce, despite three previous studies carried out by…”

The present paper describes an in-depth experimental and numerical investigation into the inplane flexural behaviour and bending moment resistances of S690 high strength steel welded I-section beams. The experimental investigation was conducted on six different welded Isections fabricated from the same batch of 5 mm thick S700MC high strength steel hot-rolled plated by means of gas metal arc welding, and involved initial local geometric imperfection measurements and twelve in-plane four-point bending tests, with six performed about the crosssection major principal axes and another six conducted about the cross-section minor principal axes. Following the experimental study, a numerical investigation was performed, where the developed finite element models were firstly validated against the test results and then used to perform parametric studies to generate further structural performance data over a broader range of cross-section sizes. The obtained experimental and numerical results were carefully analysed 2 and then adopted to evaluate the accuracy of the existing slenderness limits (for classifications of plate elements and cross-sections) and local buckling design rules for S690 high strength steel welded I-sections in bending, as set out in the European, Australian and American standards. The results of the evaluation revealed that the codified slenderness limits are generally safe when used for the classification of the constituent plate elements of the examined S690 high strength steel welded I-section beams, except for that given in the American specification for slender/non-slender outstand elements in compression. All of the three considered design standards were shown to yield accurate cross-section bending moment capacity predictions for compact (Class 1 and 2) S690 high strength steel welded I-section beams bent about both the principal axes and non-compact (Class 3) S690 high strength steel welded I-section beams bent about the major principal axes, but resulted in a rather high level of conservatism in predicting the cross-section bending moment capacities for non-compact (Class 3) S690 high strength steel welded I-sections in bending about the minor principal axes and slender (Class 4) S690 high strength steel welded I-sections subjected to both major-axis bending and minor-axis bending.

“…Ban et al [16] investigated the overall buckling behavior of high-strength steel welded section columns. Li et al [17][18] employed numerical and experimental methods to investigate 12 Q690 HS steel welded box and I-section columns. Nie et al [19] performed an experiment on eight box columns with varying cross sections, slenderness, and eccentricities.…”
