Finite Element Analysis of Earthquake Resistance Behaviors in L-Shaped Concrete-Filled Rectangular Composite Steel Tubular Columns
By using finite element software ABAQUS, the nonlinear finite element analysis of earthquake resistance behavior of L-shaped concrete-filled rectangular composite steel tubular columns is carried out, furthermore, the analysis results and the corresponding experimental results are compared. The results indicate that the finite element calculated value of ultimate bearing capacity is less than experimental value; axial compression ratio of the specimen has little affect on its ultimate bearing capacity and earthquake resistance behaviors; the results of FEM analysis can match the experiment results better, and thus, it can better reflect the earthquake resistance behaviors of the specimens.
