A building structure including a beam-to-column, and beam-to-beam structural joint connection, said joint connection cimprisint: a col-umn to provide support for said building structure; a pair of beams disposed on opposite sides of said column; wherein each of said beams has a respec-tive one end thereof attached to said column in a beam-to-column joint connection transferring gravi-ty load from said beam to said column and having sufficient strength to sustain axial tension substan-tially equal to the ultimate tensile capacity of said beam; wherein said joint connection includes: a pair of spaced apart gusset plates (34, 36) horizon-tally sandwiching said column so that said gusset plates extend along opposite sides of and are joined to both said column and said pair of beams; where-by, axial tension and moment loads caused by earthquake, severe weather, or another stressing event is sustained by said building, and whereby an extraordinary "double-span" condition for said pair of beams resulting from the loss of support by said column caused by explosive blast is also sustained by said building structure without progressive col-lapse. |
