“…This method provides noticeable improvements over the elastic plastic-hinge approach. King and Chen [223] extended this method to a member under weak-axis bending. It was found that the stiffness of the member under weak-axis bending degrades more significantly than that of the member under strong-axis bending, and thus it should be considered in the inelastic analysis.…”

Structural steel frames exhibit significantly geometric and material nonlinearities which can be captured using the second-order inelastic analysis, also known as advanced analysis. Current specifications of most modern steel design codes, e.g. American code AISC360, European code EC3, Chinese code GB50017 and Australian code AS4100 permit the use of advanced analysis methods for the direct design of steel structures to avoid tedious member capacity checks. In the past three decades, a huge number of advanced analysis and modeling methods have been developed to predict the behavior of steel and composite frames. This paper presents a comprehensive review of their developments, which focus on beam-column elements with close attention to the way to capture geometric and material nonlinearity effects. A brief outline of analysis methods and analysis tools for frames was presented in the initial part of the paper. This was followed by a discussion on the development of displacement-based, force-based and mixed beam elements with distributed plasticity and concentrated plasticity models. The modeling of frames subjected to fire and explosion was also discussed. Finally, a review of the beam-column models for composite structures including concrete-filled steel tubular (CFST) columns, composite beams and composite frames was presented.

“…To do this, the yield surface needs to be calibrated for section geometry and material behaviour and also for bending either in the weak or strong planes. Orbison and McGuier (1982) [17,40,42] and the American Institute of Steel Construction (AISC)…”

“…It is generally recognized that the real behaviour of the connections is never as ideal as assumed in the analysis. Analysis and design of steel frames with semi-rigid connections have been extensively examined Monforton and Wu [12]; Frye and Morris [13]; Lui and Chen [14]; Cunningham [15]; King [16]; King and Chen [17]; Dhillon and Malley [18]; Sekulovic and Salatic [19]; Kaveh and Moez [20]; Lógó et al [2], Wang [21]; Ihaddoudene et al [22]. Optimum design of steel frames with semi-rigid connections has also been investigated using mathematical programming techniques Xu and Grierson [23]; Almusallam [24]; Alsalloum and Almusallam [25]; Simoes [26]; Kameshki and Saka [27] and [28]; Hayalioglu and Degertekin [29], [30] and [31]; Csebfalvi [32]; Degertekin and Hayalioglu [33].…”

This paper includes description of reliability based design optimization of elasto-plastic skeletal structures under multi-parameter static loading. Presented approach is based on the assumption that the complementary strain energy of the residual forces is considered as an overall measure of the plastic performance for plastic shakedown analysis and optimal design of the structure, and this measure is an uncertain quantity responsible for resistance of the structure by assuming Gaussian distribution. The problems yield to nonlinear mathematical programming which are solved by the use of bi-level sequential quadratic algorithm. Simple portal frames are optimized to illustrate the proposed approaches.
