Finite element analysis on compressive behaviour of tin slag polymer concrete with fibre reinforced polymer composites confinement

Finite Element Analysis (FEA) forecasts how tin slag polymer concrete with confinement would react to real-world stresses, minimizing the need for a physical prototype. Currently, there is no research on FEA designated for tin slag polymer concrete with fibre reinforced polymer (FRP) confinement. The purpose of this study is to investigate the compressive behaviour of tin slag polymer concrete (TSPC) with FRP confinement through finite element method (FEM). Carbon fibre reinforced polymer (CFRP) and glass fibre reinforced polymer (GFRP) were used to enhance the compressive properties of TSPC column. A comparison was made between the finite element result and the experimental result by analysing the stress–strain response. According to the comparison, the finite element model and experimental sample for unconfined and confined TSPC share a similar bilinear stress–strain curve. It was also discovered that TSPC with GFRP confinement has substantially more accurate stress–strain curve with 4.46% compared to 13.47% for CFRP, a percentage difference of 9.01%. TSPC with CFRP confinement has higher compressive strength than GFRP. The highest strength increment from one layer to the next occurs between one and two confinement layers. According to the simulation, the failure mode of finite element model is similar to the experimental sample.
