Description	Journal: Iop Conference Series: Earth and Environmental Science L-shaped concrete-filled steel tubular column (CFST) has the advantages such as high bearing capacity,good ductility and high utilization rate of internal space of the building, thus avoiding the occurrence of column shearing in the indoor use space. In engineering application, the axial bearing capacity of CFST is very important for the stability of structure, and is an extremely significant mechanical performance index. Finite element (FE) models are established to calculate the load-deformation curves and the calculated results are verified by the experiments. On this basis of FE models, the parameters of wide-to-limb ratio, steel yield strength, concrete cylinder strength and steel thickness are analyzed. It indicates that the calculation method of axial bearing capacity based on superposition theory is basically suitable for L-shaped concrete filled stub column structure in the ranges of the parameters. Keywords: CFST; L-shaped; column; axial compression; ultimate strength.
