“…For the validation of the numerical model of the composite beam, the experimental investigation performed by Vasdravellis et al [11], [12] on a simply supported composite beams under a single point load is considered. Details of the test are reported in Vasdravellis et al [11], [12].…”

This paper presents the numerical assess of the robustness of a seismic-resistant steel building with self-centering moment resisting frames against progressive collapse. The numerical analyses were carried out using a 3D model developed in ABAQUS. The 3D model considers the effect of the composite slab, where composite beams and their shear connectors were modeled with a combination of shell, beam and nonlinear connector elements. All the beam-column and beam-to-beam connections were modeled using nonlinear connector elements with appropriate failure criteria, calibrated against previous experimental results. The self-centering moment resisting frame where a sudden column loss was simulated was modelled using 3D solid elements to accurately capture its local and global nonlinear behavior. Quasi-static nonlinear analyses were carried out to identify all possible failure modes and to investigate the effect of the floor slab on the overall progressive collapse resistance. Nonlinear dynamic analyses were also carried out to predict the true dynamic response and evaluate the acceptance criteria of current building design guidelines.

“…Despite the large amount of available experimental data on the flexural behaviour of composite beams [5][6][7], experimental data on the behaviour of composite beams under combined loading is rather limited. The effects of axial tension on the sagging and hogging moment regions of composite beams were studied in previous research by the authors [8,9]. In this work, the ultimate strength of composite beams subjected to combined actions was investigated by a large experimental programme, rigid plastic sectional analyses and extensive finite element simulations.…”

“…The authors recently studied the behaviour and design of composite beams under the four combinations of flexure and axial loads [32][33][34][35] namely: tension and negative bending, tension and positive bending, compression and negative bending and compression and positive bending respectively. Each of these studies contains an experimental series, a finite element analysis and design recommendations for the M-N interaction of each respective loading combination.…”

“…The study contained herein is the culmination of a larger research project aimed to determine the effect of axial load on the flexural and shear capacity of composite beams [12,[31][32][33][34][35]. This paper presents the results of a finite element model and proposes design models for the reduction in flexural and shear capacity of a member in the presence of axial load.…”
