Gusset plate connection of braced beam to column

Abstract

A joint connection structure of a building framework includes a column assembly including a column and a pair of gusset plates connected to the column on opposite sides of the column and extending laterally outward from the column. A full-length beam assembly includes a full-length beam having upper and lower flanges and an end portion received between the gusset plates. The full-length beam is bolted to the gusset plates of the column assembly to connect the full-length beam assembly to the column assembly. A brace has an end portion received between the gusset plates and makes an angle with the beam and with the column. The brace is bolted to the gusset plates at the end portion of the brace.

         13 . The joint connection structure of  claim 12  wherein the slotted bolt holes are slotted in a direction generally parallel to a longitudinal axis of the beam. 
     
     
         14 . The joint connection structure of  claim 12  wherein the slotted bolt holes are arranged in rows near at least one of a top and bottom edge of said at least one of the gusset plates. 
     
     
         15 . The joint connection structure of  claim 1  further comprising an adjustable beam seat attached to the column and supporting the full-length beam assembly at least partially between the gusset plates, the beam seat being configured to move the full-length beam assembly relative to the gusset plates prior to bolting the full-length beam assembly to the column assembly. 
     
     
         16 . The joint connection structure of  claim 1  wherein the full-length beam assembly comprises angle irons attached to the upper flange and angle irons attached to the lower flange, the angle irons being bolted to the gusset plates. 
     
     
         17 . A joint connection structure of a building framework comprising:
 a column assembly including a column and a pair of gusset plates connected to the column on opposite sides of the column and extending laterally outward from the column;   a full-length beam assembly including a full-length beam having upper and lower flanges and an end portion received between the gusset plates; and   an adjustable beam seat attached to the column and supporting the full-length beam assembly at least partially between the gusset plates, the adjustable beam seat comprising a first portion fixed to the column assembly and a second portion movably attached to the first portion, the second portion does not extend through a hole in the beam assembly or the column assembly for permanent attachment of the full-length beam assembly to the column assembly, the adjustable beam seat being configured to move the full-length beam assembly relative to the gusset plates by movement of the second portion relative to the first portion.
