ABSTRACT:
Fittings for connecting H-shaped beams and columns of a steel frame construction, each fitting comprising an L-shaped outer fitting member connecting an outer surface of a flange of the beam to the column by means of bolts and an L-shaped inner fitting member connecting an inner surface of the flange of the beam to the column by means of bolts having a space for receiving therein a web of the beam, thereby embracing the flange of the beam between the L-shaped outer and inner fitting members to provide two surface frictional engagements. A column side plate of each the L-shaped fitting members successively increases its thickness from a free end to a portion connected to the beam side plate thereof. A method of connecting a column and a beam having an H-shaped section, wherein after the L-shaped outer fitting member for a lower flange of the beam has been connected to the column, the other outer and inner L-shaped fitting members are temporarily fixed to the beam such that the overall length of the thus assembled beam and fittings is shorter than their ultimate length. Then the beam and fittings are placed on the first outer fitting member and all the fitting members are ultimately bolted to the column and the beam.
