“…Many research studies have been conducted to investigate the behavior of stainless-steel members and provide reliable analytical tools for designers. Most of these studies focus on elements such as stainless steel beams [1][2][3], columns [4][5][6], and composite structures [7][8][9]. The stainless steel has high ductility; hence the rotational capacity of stainless steel connections and the overall ductility of the structures are further improved.…”

Considering the significant strain‐hardening and ductility characteristics of stainless steel and the influential role of beam to column joints in the overall response of structures, a clear understanding of their moment rotation behaviour appears fundamental. In the present study, a review of the European design code for three typical semi‐continuous beam‐to‐column joints (extended end plate, flush end plate and top‐and‐seat angle connections) is first carried out. Then, using a hybrid modelling strategy with uncoupled elastic‐plastic springs for the bolts and shell elements for the members, more refined 3D finite element (FE) models are developed and validated against available test results. An equivalent stress definition is then proposed for calculating the joint moment resistance. Finally, the initial rotational stiffness, moment resistance, rotation capacity, and failure patterns are used to evaluate critically the accuracy of the predictions of the European design code. As a result, the need for more comprehensive design guidance in accordance with the observed findings is pointed out.

“…There are few research studies on stainless steel-concrete composite structures such as concrete-filled stainless steel columns (e.g. [18][19][20][21]) and composite concretestainless steel beams [22]. To date, it seems to have been little or no research, at least in the public domain, into the web-post buckling of cellular beams made from stainless steel.…”

Cellular steel beams are widely used in modern constructions to achieve long spans and to provide passage for service installations such as ducts and cables. The present paper is concerned with the use of stainless steel in cellular beams. In fact, available design methods to calculate the shear strength of web‐post are applicable only to carbon steel that exhibits a linearly‐elastic behaviour with a clear yield point followed by plastic deformation with little amount of strain hardening. Conversely, stainless steel exhibits a non‐linear stress‐strain relationship with high level of strain hardening. Consequently, new design provisions for the web‐post buckling of cellular beams made from stainless steel capable of exploiting the material strain hardening are highly desirable. Since no experimental investigations are available in literature for cellular beams made from stainless steel, finite‐element models have been developed and validated against tests conducted for carbon steel cellular beams. The structural behaviour of stainless steel cellular beams with various geometries and material characteristics is investigated through a large number of finite element analyses and a simple mechanical model for the Web‐Post Buckling (WPB) failure is developed and calibrated against the numerical results to provide the basis of a reliable design method.

“…Hassanein and Silvestre [27] studied the bending mechanical properties of tilted duplex SS beams using a finite element model for analysis and concluded that the bending prediction provided by EN 1993-1-4 is conservative. Shamass et al [28,29] provided several prediction methods for bending performance of SS composite beams based on the continuous strength method.…”

In this paper, the flexural characteristics of stainless steel (SS) reinforced concrete beams are studied and analyzed. We mainly focus on their crack mode, failure mode, load-deflection curve, and bearing capacity. Six beams with test parameters, including the diameter of reinforcement, the type of the reinforcement, and the stirrup spacing, were tested in 4-point bending. The test results indicate that the failure mode of SS reinforced concrete beam can be divided into three stages: elastic stage, cracking stage, and failure stage. The midspan section deformation of SS reinforced concrete beam conforms to the assumption of plane section. Under the same reinforcement condition, the normal section and the oblique section bearing capacities of the SS reinforced concrete beams are significantly higher than those of the ordinary reinforced concrete beams. In addition, the prediction of cracking moment and bearing capacity calculated by ACI 318-14 and GB 50010-2010 was also evaluated. The calculation results of the two codes were safe and conservative, and GB 50010-2010 provided more accurate prediction of cracking moments. Furthermore, to verify the reliability of the test results, finite element models were established and the analytical results corroborated well with the test results.
