Finite Element Analyze on the CFRP Steel Reinforced Concrete Filled with Steel Tube Column under Biaxial Load

Abstract:

The paper focuses on the research of mechanical behavior of the CFRP steel reinforced concrete filled with steel tube column under biaxial load. The authors make a simulated analysis mode with the general finite element analyze software, ABAQUS. By the way of unit selecting, meshing, contact setting, the mode is calculated by the ABAQUS/Standard which is used to analyze the mechanical behavior of the specimens. Based on comparing the load-displacement curves under different axial compression ratios, it can conclude that with the increasing of compression, the ultimate load reduces obviously. At the same time, the ductility coefficient also descended slowly. All the ductility coefficients of different specimens are all larger than 2, which meet the code very well. So the mechanical behavior of the column is very well.
