A building structure including a beam-to-column, and beam-to-beam structural joint connection, said joint connection cimprisint: a column 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 respective one end thereof attached to said column in a beam-to-column joint connection transferring gravity load from said beam to said column and having sufficient strength to sustain axial tension substantially equal to the ultimate tensile capacity of said beam; wherein said joint connection includes: a pair of spaced apart gusset plates (34, 36) horizontally 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; whereby, 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 collapse.
