【Abstract】 The nonlinear numerical simulation analysis was conducted to investigate the mechanical behaviors of GFRP Tubed Reinforced Concrete Column with circular section under axial compression by ANSYSsoftware and the calculated results were agreed well with the experimental ones.The results show that the 3D finite element analysis model is effective.Using this model, the stress mechanism of the GFRP casing reinforced concrete column is analyzedunder Axial Compressionand the influence of casing thickness、concrete strength and the ratio of length to diameter on the mechanical properties of the members.The resultsindicate FEM can well simulate the behavior of concrete columns under uniaxial loading when parameters andnumerical models are carefully chosen.更多还原
