| Abstract: | An experimental study on the shear resistance performance of 20 square concrete-filled steel tube （CFST） columns was conducted. The load-displacement curves of CFST columns subjected to shearing force were obtained. Meanwhile, the mechanical properties and the failure modes were analysed. The influences of parameters, including shear span ratio and axial compression ratio, upon the shearing behaviour were also investigated. The experimental results indicate that CFST columns have favourable shear bearing capacity and plastic property. Calculation formula of shear bearing capacity for CFST columns in the practical engineering design were recommended. |
