“…In order to better capture the structural behaviour under large deformations, different types of element are sometimes combined and are recognised as multi-scale or hybrid models. By modelling different parts of the structure on different scales, both the overall structural behaviour and local nonlinear damages can be well captured [244,245]. More importantly, both the number of elements and the computational cost can be significantly reduced.…”

“…Qin et al [19] and Wang et al [6] investigated beam-to-SHS column connections under a middle column loss scenario and proposed a reinforcing technique by using bolted cover plates to develop full plastic strength of the beams under the large deformation phase and take full advantage of CA produced by axial tension. Wang et al [20] studied the progressive collapse performance of steel beam to concrete-filled steel tubular (CFST) column connections and concluded that the frame structure with these joints was enabled to form the resistance mechanism and can prevent the occurrence of progressive collapse after the failure of column connected to joints. Zhong et al [21] studied the anti-progressive collapse performance of welded unreinforced flange-bolted web connection (WUF), top-seat angle with double web angle connection (TSDWA), and double web angle connection (DWA) of a steel frame.…”

“…Hajjar et al 14 proposed a 3-D modeling of interior beam-to-column composite connections. Wang et al 15 investigated several types of CFST column to steel beam connections by using two types of CFST with square and circular sections with outside stiffening ring plate or with penetrating ring plate. It was pointed out that these joints could improve the resistant of the progressive collapse when compared with the other types of connections.…”

Composite columns such as concrete-filled steel tube (CFST) were adopted in many building constructions in recent years because of carrying high loading with the ability to resist buckling and small cross-sectional area. The high behavior of the CFST columns is due to the interaction between steel and concrete which called the composite action. This type of composite column without main and tie reinforcements embedded in concrete gives high axial compression strength to resist the external loadings with the economic sectional area. The work presented in this article includes simulation models that tested by other researchers and a parametric study on the performance of frames that connected steel beam by composed columns of circular CFST that subjected to lateral loading. A finite element (FE) approach is adopted to simulate the models by ANSYS software. All models consider the linear and nonlinear material analysis of the concrete and steel. The validity of the developed model was examined by comparing with the experimental data founded in the literature. Different parameters such as the ratio of the axial load, the slenderness ratio of CFST column, the linear stiffness ratio of the beamcolumn, the steel yield strength of the beam, the steel yield strength of the tube, and concrete strength on the performance of the composite frames were also studied and the load-deformation performance was obtained over the different cases of the study. Analysis results by FE modeling were in good agreement with the experimental results.
