A method in which prestress is introduced to a building structure of a multi-story construction from an RC foundation to RC columns and beams, includes: buring a sheath in advance, through which a tendon is inserted, at required positions in the foundation and in the RC columns and beams on each story and performing construction as an RC structure up to the uppermost story; and then inserting the tendon into the sheath, fixing the tendonunder tension, and thereby introducing the prestress to the entire RC building structure from the foundation to the column and beam. Accordingly, seismic performance of the entire building structure designed as the RC structure is greatly improved. Rebar in the designed RC structure building responds to a normal load and a small or medium-sized earthquake and, during a massive earthquake that registers a Seismic Intensity equal to or greater than that assumed in design, the complement of the introduced prestress makes it possible for the structure to survive even a massive earthquake that registers up to a Seismic Intensity 7.
