This invention discloses a concrete column model and its casting method, as well as a method for testing the buckling of reinforcement in the model. The concrete column model includes a column body, with the middle part of the column body serving as the testing section. The two ends of the testing section are the upper end and the lower end, respectively. The testing section, the upper end, and the lower end are integrally cast. At least one first hard plate is provided on the joint surface between the testing section and the upper end, and at least one second hard plate is provided on the joint surface between the testing section and the lower end.
