The utility model relates to a civil engineering structure, in particular to a connected node of a steel girder and a combined steel and concrete column. The connected node comprises the steel girder and the combined steel and concrete column; a sleeve formed through the end-to-end welding of a prefabricated steel plate is sleeved on the combined steel and concrete column; and a fixed plate at the end part of the steel girder is connected with the prefabricated steel plate forming the sleeve through a bolt. Therefore, the limit value of the axial compression of the column can be effectively increased, the sectional dimension of the column is effectively reduced, the building use space is increased, a short column can be prevented from occurring, the arrangement number of shear connectors at a column end is greatly reduced, the cost can be effectively reduced, and the construction progress is speeded up. The utility model is suitable for components in the form of different sections such as the T-shaped section, the L-shaped section, the cross section and the like as well as different types of components such as the column, the shear wall embedded column, the irregular column, the short-pier shear wall embedded column and the like; and in addition, the construction difficulties caused by concrete pouring in a core steel pipe concrete structure are avoided.
