PURPOSE: A manufacturing method of a composite structural frame is provided to remove restriction on space utilization of a building by columns and to function as a favorable structure against the load from unexpected direction such as an earthquake. CONSTITUTION: The manufacturing method of a composite structural frame comprises the steps of: adding primary load downward on a spot where the positive moment of shape steel is at the maximum to make the displacement of shape steel within the elastic limit, arranging and giving tension to tendon on the top of the shape steel, laying a sheath under the shape steel and placing lower concrete; after curing the lower concrete, removing the primary load; adding secondary load upward on the spot where the primary load is added, placing upper concrete on the top of the shape steel where tendon is arranged, arranging tendon on the lower part of the shape steel, then giving tension; after curing the surface of an upper structure, removing the secondary load.
