Abstract
A method of connecting beams having an H-shaped section to a column having an H-shaped section of a steel frame construction with upper and lower flange fittings. The flange fitting comprises a substantially rectangular base plate to be connected to the column having centrally a continuous thicker portion from which the base plate is tapered toward opposite ends of the base plate, a supporting plate projecting from the thicker portion for supporting a flange of the beam and a reinforcement on the base plate forming a T-shaped portion with the supporting plate. First the supporting plate of the upper flange fitting is secured to one end of an upper flange of the beam in end-to-end relationship and the base plate of the lower flange fitting is bolted in position to the column. Thereafter, one end of a lower flange of the beam is located onto the supporting plate of the lower flange fitting, and the lower flange of the upper flange fitting are secured to the supporting plate of the lower flange fitting and the surface of the column, respectively.
