The invention belongs to the technical field of steel structure design, and provides a calculation method for an exposed steel column hinged column foot, the steel column hinged column foot comprises a steel column, a column foot bottom plate and a concrete foundation, the column foot bottom plate is welded at the bottom of the steel column and is fixedly connected with the concrete foundation through a plurality of foundation bolts, and the concrete foundation is fixedly connected with the column foot bottom plate. The calculated thickness tb of the column foot bottom plate is determined by the following formula: tb = max (tb pressure, tb pull, 20mm); wherein the tb pressure is the calculated thickness of the column foot bottom plate under the action of the vertical pressure, the tb pull is the calculated thickness of the column foot bottom plate under the action of the vertical pull, and the tb pressure and the tb pull are both obtained by adopting plastic section modulus calculation. According to the metho
