Highlights Analytical model for confining pressure exerted by outer FRP and inner steel tube on sandwiched concrete in hybrid FRP-Concrete-Steel Double Skin Tubular Columns (DSTC) under axial compression is proposed. Analysis-oriented model is proposed for predicting the axial stress–strain behavior of DSTC and validated with available experimental data from the literature.
Abstract An analytical model is proposed for confinement pressure exerted by outer fibre-reinforced polymer (FRP) and inner steel tube on sandwiched concrete in hybrid FRP-concrete-steel double skin tubular columns (DSTC) under axial compression assuming displacement compatibility between both FRP-concrete and steel–concrete interfaces. Next, using the proposed analytical model, an analysis-oriented model is presented to predict the uniaxial behavior of hybrid FRP-concrete-steel DSTC. Comparison with available test results from the literature shows that the proposed model provides reasonably good predictions compared to other existing models.
