Column flange and stiffener plate construction
Abstract
Abstract A BEAM IS PROVIDED WITH AN END CONSTRUCTION FOR RIGID CONNECTION TO VERTICAL COLUMN. ONE END OF THE BEAM IS PROVIDED WITH A RIGIDLY CONNECTED VERTICALLY EXTENDING SUPPORT PLATE. A STIFFENER PLATE PROVIDED WITH A CENTRALLY LOCATED, VERTICALLY EXTENDING ELONGATED SLOT IS INTERPOSED BETWEEN ONE FLANGE OF THE COLUMN AND THE SUPPORT PLATES WITH ONE SIDE OF THE STIFFENER PLATE IN SURFACE TO SURFACE CONTACT WITH ADJACENT COLUMN FLANGE. THE STIFFENER PLATE IS WELDED TO THE COLUMN FLANGE, WITH WELD MATERIAL COMPLETELY OCCUPLYING THE ELONGATED VERTICAL SLOT TO THEREBY RIGIDLY CONNECT THE STIFFENER PLATE TO THE OPPOSING FLANGE OF THE COLUMN AND THEREBY INCREASE THE EFFECTIVE THICKNESS OF THE COLUMN FLANGE. THE SUPPORT PLATE ABUTS THE OPPOSITE SIDE OF THE STIFFENER PLATE. A PLURALITY OF HIGH STRENGTH BOLTS EXTEND THROUGH THE SUPPORT PLATE, STIFFENER PLATE AND COLUMN FLANGE TO PROVIDE A RIGID CONNECTION, WITH THE BOLTS BEING LOCATED AND ARRANGED IN ROWS ON OPPOSITE SIDES OF THE WELDED SLOT-JOINTED SO THAT THE FORCE APPLIED TO THE COLUMN FLANGE IS ROTATED 90* AND DISTRIBUTED THROUGHOUT THE WEB OF THE COLUMN.
