“…Finally, in the frame of a vast experimental and numerical study dealing with transversally stiffened hybrid steel plate girders and concentrated loading, Chacon et al [23,24] pointed out conclusions about the effect of the hybrid grade Φ h = f yf /f yw on the resistance to patch loading. These conclusions are summarized in a twofold fashion herein.…”

“…This feature proves unsafe for unstiffened girders with stiff flanges and largely spaced transverse stiffeners [23,24]. In the following section, an assessment of such a statement is also presented for the case in which the girders present a longitudinal stiffener with varying flexural/torsional inertia and position.…”

“…In addition, all numerical simulations were performed by following the current European guidelines EN1993-1-Annex C, which allow designers to use FEAnalyses. In a previous work performed by the authors, the validity of these guidelines when developing numerical models on transversally stiffened plate girders subjected to patch loading was pointed out [32,23,24].…”

“…In this work, the resistance of longitudinally stiffened hybrid steel plate girders subjected to patch loading is studied. The paper is based upon the conclusions previously given in [23,24] concerning the resistance of unstiffened hybrid girders subjected to patch loading. In such studies, it is demonstrated that the varying yield strength of the flange f yf (and thus, the hybrid grade Φ h ) does not play any role in the resistance of girders subjected to concentrated loading.…”

“…The paper is based upon a vast numerical study as well as on proper comparisons of the results with the actual formulation of EN9913-1-5 [25]. Eventually, the design proposal given in [24] is extended to the case of girders presenting longitudinal stiffening. This proposal is in full accordance with the procedure presently implemented in EN19931-5.…”

A comprehensive investigation into the behaviour of structural stainless steel members under concentrated transverse loading is presented in this paper. A total of 34 member tests and over 500 finite element simulations have been performed covering three types of concentrated transverse loading – internal one‐flange, internal two‐flange and end one‐flange loading, three stainless steel grades – austenitic, duplex and ferritic and key influential parameters such as bearing length, web slenderness and beam span. The results have shown that existing design recommendations are conservative and that there is considerable scope for the development of more economical design guidance. New design equations are proposed that offer 10% to 20% improvements in capacity predictions over the current design formulae in EN 1993‐1‐4. These proposed design equations are to be included in the next revision of the European standards. An alternative design approach based on numerically generated reference loads – i.e. the plastic collapse and elastic buckling loads – in conjunction with strength curves, has also been proposed. This advanced FE‐based design approach allows the extension of the design scope to non‐standard cases, such as webs with partial depth stiffeners and members with web holes. The reliability of both design approaches has been successfully verified by statistical analysis.
