- 7. The combination recited in claim 1,
wherein said gusset plates are fixedly attached with respect to said beam by a cover plate disposed on the top of said beam and a cover plate disposed on the bottom of said beam, said cover plates being disposed between said gusset plates, wherein said cover plates are fixedly attached to said beam for a distance extending from substantially the same, or slightly more than, the distance said gusset plates extend along said beam, and wherein said cover plates are welded to said gusset plates.
- 8. The combination recited in claim 1 wherein is included two or more stiffener plates welded within said column at or near the location said gusset plates are welded to said column, strengthening said column at said location.
- 9. The combination recited in claim 8 wherein said stiffener plates extend in the longitudinal direction of said column.
- 10. The combination recited in claim 8 wherein said stiffener plates extend perpendicular to the longitudinal direction of said column.
- 11. A structural joint connection comprising,
a column of sufficient size and strength to provide columnar support for a building, tower and the like, said column having at least two flanges, wherein each said flange has a face, a beam of sufficient size and strength to provide support for the floor of a building, tower and the like, said beam having one end disposed near said column, a pair of gusset plates, wherein said gusset plates extend along opposite sides of said beam in face-to-face, parallel relationship with each other, wherein said gusset plates are fixedly attached with respect to said beam, wherein both said gusset plates terminate at the face of the same flange of said column, and wherein said gusset plates are attached to said face by welds, said welds extending along the longitudinal direction of said column.
- 12. The combination recited in claim 11 wherein said welds comprise any one or combination of fillet welds, full-penetration groove welds, partial-penetration groove welds, flare-bevel groove welds and any other suitable weld type.
- 13. The combination recited in claim 11 wherein is included a second beam,
wherein is included a second pair of gusset plates extending along opposite sides of said second beam in parallel, face-to-face relationship with each other, wherein said second pair of gusset plates are fixedly attached with respect to said second beam, wherein both gusset plates of said second pair of gusset plates terminate at the face of the other flange, of said column, and wherein said second pair of gusset plates are attached to said other face by welds, said welds extending along the longitudinal direction of said column.
- 14. A structural joint connection comprising,
a column adapted for use as permanent, columnar support for buildings, towers and similarly heavy structures, said column having at least two flanges, a beam having at least two flanges, a pair of gusset plates in parallel, face-to-face relationship with each other, said gusset plates disposed on opposite sides of said beam and extending along the flanges of said beam, wherein said beam is fixedly attached with respect to said parallel gusset plates in a strong, moment-resisting connection, wherein both said gusset plates abut the same flange of said column, wherein each said parallel gusset plate is welded along an end thereof to said same flange of said column, and wherein no additional gusset plate is attached to said column and the end of either of said parallel gusset plates, in the same plane as said parallel gusset plates.
- 15. The combination recited in claim 14 wherein each said parallel gusset plate is welded along an end thereof to said flange of said column, by being welded to the end of said flange.
- 16. The combination recited in claim 14 wherein each said parallel gusset plate is welded along an end thereof to said flange of said column, by being welded to the face of said flange.
- 17. The combination recited in claim 14 wherein each said parallel gusset plate is welded to the face of said flange, at a location inwardly from the outer edge of said flange.
- 18. The combination recited in claim 14 wherein is included,
two vertical shear plates disposed on opposite sides of said beam from each other and fixedly attached between said beam and said gusset plates, and wherein said vertical shear plates are disposed at or near the end of said gusset plates along said beam, away from said column.
- 19. In combination,
a column for providing columnar support for a building and similarly heavy structure, said column having at least one face, a beam, two parallel gusset plates, in face-to-face relationship, and extending along opposite sides of said beam, and fixedly attached with respect to said beam in a strong, moment-resisting connection, wherein said two parallel gusset plates are both welded to the same face of said column in a strong, moment-resisting connection.
