PURPOSE: A composite beam structure is provided to resist large stress and to improve adiabatic efficiency. CONSTITUTION: A composite beam structure (1) comprises a steel bracket (20), a stud bolt (50), a shear resistance plate, a stirrup (90), a plurality of reinforcing bars (97), and a cover (100). The steel bracket is fixed to a beam (10) and comprises a hollow unit inside. The stud bolt is fixed to an upper surface (35) of the steel bracket. The shear resistance plate is installed inside the steel bracket and comprises two vertical plates and a horizontal plate connecting the lower part of the vertical plates. The stirrup is formed at a longitudinal direction of a U-shaped PC member (15) at regular intervals in order to wrap the shear resistance plate and the stud bolt. The reinforcing bars are installed in a longitudinal direction of the U-shaped PC member in the inside of the stirrup. The cover is located on an upper part (63) of the shear resistance plate and blocks the upper surface of the shear resistance plate.
