Abstract
A steel column base member for connecting an H-shaped structural steel column member to a concrete foundation, which base plate member is an integral cast or forged body comprising a bottom plate member to engage the foundation, an H-shaped projection upwardly extending from the bottom plate member and having J-shaped grooves formed along both edges of top surface of projection the width of web of projection being broader than that of web of column member, so as to effect groove welding between the bottom surface of the steel column member and the J-shaped grooved surfaces, and fillet welding both side of web of the column member and base plate member. A method of connecting an H-shaped steel column member to a base plate member is characterized by, effecting fillet welding along between lower ends of a web of column member and a top surface of base plate member, effecting J-shaped groove welding along betweeen J-shaped groove surfaces of base plate member and the bottom surfaces of flanges of steel column member, and fillet welding along between the inner lower ends of flanges of a steel column member and the top surfaces of flanges of projection.
