PROBLEM TO BE SOLVED: To provide a beam structure, obtaining a beam structure satisfying the strength and vibrational property using a general beam material such as standard H-shape steel in the case of realizing a large span having a large area floor surrounded with a girder in a building having a large superimposed load, dispensing with a beam penetrating hole, reducing the cost, and flexibly coping with a free piping plan, and extension and alteration of a piping route. SOLUTION: An upper beam 2a and a beam 3 of the girder 2 are joined to each other by a bolt, and the joining end part of the beam 3 is provided with a brace 4 obliquely rising from the lower beam 2b within a vertical plane to support the joining end part of the beam 3. The lower end part of the tappet material 4 is joined to the lower beam 2b by a bolt, and the upper end part thereof is joined to the lower surface of the joining end part of the beam 3 by a bolt. The stress and deflection properties are improved by a truss formed on the joining end part, and the stress is reduced and structural rigidity is increased so as to reduce floor vibration and reduce the sectional area of the beam material body of the beam.
