| 摘要 |
A steel column base member for connecting a hollow or box-shaped structural steel column member having square, rectangular or annular section, to a concrete foundation, which base plate member is an integral cast or forged body comprising a bottom plate member to engage the foundation, a box-shaped projection upwardly extending from the bottom plate member and having J-shaped grooves formed along overall outer edges of top surface of projection the width of web of projection being broader than thickness of column member, so as to effect groove welding between the bottom surface of the steel column member and the J-shaped grooved surfaces. A method of connecting an hollow or box-shaped steel column member to a base plate member is characterized by, effective J-shaped groove welding along between J-shaped groove surfaces of base plate member and the bottom surfaces of steel column member.
