A fabricated special-shaped-column concrete frame structure comprises a precast special-shaped column and a precast beam. The precast beam comprises a precast main beam and a precast secondary beam, the precast special-shaped column is divided into a precast upper column and a precast lower column in the nodal area, pre-buried connecting steel plates are arranged on the lower end surface of the precast upper column and the upper end surface of the precast lower column correspondingly, and the pre-buried connecting steel plate on the precast upper column and the pre-buried connecting steel plate on the precast lower column are welded on the position of the nodal area; meanwhile, an in-column vertical load-bearing reinforcing steel bar configured in the precast column and the corresponding pre-buried connecting steel plate are welded, and the in-column vertical load-bearing reinforcing steel bar is indirectly connected through the pre-buried connecting steel plate on the position of the nodal area; a first invisible corbel is precast at one end, connected with the precast main beam, of the precast lower column; and a second invisible corbel is precast on one side, connected with the precast secondary beam, of the precast main beam. The fabricated special-shaped-column concrete frame structure is simple, convenient and reliable, and does not pollute the environment.
