“…The same study showed that the concrete strength, steel yield strength, and steel tube thickness all affected the behavior of circular STCC stub columns. Wang et al [54] investigated the compressive behavior of carbon fiber-reinforced polymer (CFRP) steel composite tube steel-reinforced columns with highstrength concrete. The study was conducted using a combination of experimental and numerical methods.…”

Concrete, as a complex and anisotropic material, poses challenges in accurately simulating its behavior in numerical simulations. This paper focuses on selecting an appropriate constitutive model for simulating the behavior of a steel–concrete composite column using finite element analysis under compression and push-out tests. Two models are analyzed and compared, namely, Drucker–Prager and concrete damage plasticity. The results demonstrate that the concrete damage plasticity model outperforms the Drucker–Prager model in all six test cases, indicating its superior accuracy in capturing the composite column’s behavior. This study enhances the reliability of numerical simulations for steel–concrete composite structures by choosing the most suitable constitutive model, parallel with extensive sensitivity analysis and model calibration. The findings emphasize the significance of meticulous model selection and precise parameter definition for achieving accurate predictions of concrete behavior. This research contributes to advancing the understanding and modeling of concrete’s intricate behavior in structural analyses.

“…In reviewing the literature, it seems that the analytical model proposed by Lim and Ozbakkaloglu (2015b) may be extended to F-STC columns if modified by adding the confining stress of steel tube, as discusses in this paper. In addition, some experimental studies have been made to investigate the performance of F-STC columns under concentric compression (Guo et al, 2017(Guo et al, , 2019Liu et al, 2018Liu et al, , 2019Wang et al, 2018), eccentric compression (Xu et al, 2020a), and reversed cyclic loads (Cai et al, 2016;Wang et al, 2019). Xu et al (2020b) proposed a design-oriented model for circular F-STC columns under concentric compression, followed by the development of a design method for eccentrically loaded F-STC columns (Xu et al, 2020c).…”

The fiber reinforced polymer (FRP)-steel composite tubed (F-STC) column is characterized by high strength and deformability as well as the tube corrosion resistance provided by the FRP. This study aims to find a suitable analytical model for F-STC columns, based on the existing analytical models for confined concrete columns where each typically consists of the stress–strain relationship of actively confined concrete, a lateral strain equation, and the confining stress. A database of 66 tests (61 reported plus 5 added) is established and used to examine the existing analytical models. However, existing models fail to predict the initial stiffness of F-STC columns with lower diameter-to-thickness ratio of steel tube and the correct development of tube stresses. To this end, an incoordination coefficient of axial strains is proposed to account for the different axial strains between the steel tube and concrete. Lastly, after a close examination on the existing analytical models, a modified Teng’s model is proposed. The results predicted by the proposed analytical model generally match well with the test results of F-STC columns.
