The invention discloses an SCS concrete filled steel tube bridge pier with shear nails added at bottom. The SCS concrete filled steel tube bridge pier comprises an outer steel tube, an inner steel tube, a top end shear resistant structure, a bottom end shear resistant structure and a concrete structure. The inner steel tube is sleeved inside the outer steel tube, the top end shear resistant structure is distributed between the top end of the outer steel tube and the top end of the inner steel tube, the bottom end shear resistant structure is distributed between the bottom end of the outer steel tube and the bottom end of the inner steel tube, the concrete structure is molded by pouring concrete filled in a cavity between the outer steel tube and the inner tube after the top end shear resistant structure and the bottom end shear resistant structure are distributed, the inner steel tube is a round steel tube, the outer steel tube and the inner steel tube are coaxially distributed, the outer steel tube is an outer steel tube one or two, the shape of the cross section of the outer steel tube one is a circle, and the shape of the cross section of the outer steel tube two is a rectangle or regular polygon. According to the SCS concrete filled steel tube bridge pier with stiffening ribs added at the bottom, the structure is simple, the design is reasonable, the construction is convenient, the construction cost is low, the mechanical property and the usage effect are good, and problems in concrete filled steel tube bridge piers are solved.
