The invention relates to a special shape column. The shape of the cross section of the special shape column is a '-' shape, a T shape, a U shape, an L shape, a crossed shape, a square shape, an oval shape or a circular shape. The invention is characterized in that the special shape column comprises reinforced concrete and steel ribs, wherein the steel ribs are positioned in the reinforced concrete, and the reinforced concrete is in a structure with combined self compact concrete and reinforced steel bars. Thereby, the structure of the special shape column can effectively reduce the unnecessary structure protrusion in the building structure, the condition of the surface formed by the self compact concrete is good, the casting and filling compactness can be easily realized, the gripping force of the reinforced steel bars can be effectively improved, the column structure with higher intensity can be obtained, and the invention can be perfectly applied to structures with high and strong carrying force and high or ultrahigh structures, has obvious environmental benefits, economic benefits and social benefits, can particularly and effectively reinforce the indexes such as pressure resistance strength, density, chopping and pulling strength, folding strength, elastic modulus and the like, and is applicable to structures of bridges, garages, retaining walls, protective walls, ordinary buildings, high buildings or ultrahigh buildings and the like.
