“…Zona et al [355] extended the displacement-based element developed by Dall'Asta and Zona [309] to simulate the inelastic seismic behaviour of composite frames. The nonlinear inelastic analysis of composite frames carried out by Iu [356] was extended from the refined plastic-hinge model developed by Iu [227] for composite beams.…”

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.

“…A large number of experimental tests on composite structure joints were also carried out (Henriques et al, 2013, 2015; Rong et al, 2012; Seo et al, 2011; Tao et al, 2013; Wang et al, 2018; Zhang and Jia, 2016; Zhang et al, 2012). Since the 21st century, the numerical simulation technology has been rapidly developed and finite element method has been applied to simulate the mechanical behavior of the composite nodes and frames (Chiorean, 2013; El-Tawil and Deierlein, 2001; Hu et al, 2012; Iu, 2016; Liu et al, 2011; Ngo-Huu and Kim, 2012; Wang et al, 2013). The simulation results in good agreement with the experimental results indicate that the finite element analysis can be an effective approach for the study.…”

The structural performance of a frame joint is particularly important, which can determine the safe state of the global structure. For this reason, the seismic performance of the truss steel reinforced concrete (SRC) beam-column frame joints is investigated by the experimental study and the nonlinear finite element modeling. The main design parameters include the section size of the web rods, the axial compression ratio and the section size of I-steel. The failure mechanism, load-displacement skeleton curve, the ductility and energy dissipation capacity, and shear deformation in the core zone of the truss SRC beam-column joints are studied. A formula is put forward to describe the shear bearing-capacity of the joints. The results indicate that the truss SRC beam-column frame joints generally have good seismic performance. The size of steel and web members have impact on the seismic performance of the truss SRC beam-column joints, and the axial compression ratio is an important factor that impacts the hysteresis behavior and energy dissipation. The proposed shear bearing-capacity formula can objectively reflect the performance of the joints.
