An aircraft deck support system includes horizontal deck support beams connected to the aircraft's frames. Each deck support beam has a plurality of machined, generally T-shaped supports. Each T-shaped support includes either a horizontal recess or a raised surface formed in a deck support beam upper chord and a U-shaped aperture formed in a beam web. The T-shaped support matably receives a cross-support beam attachment flange perpendicularly aligned with the deck support beams. Each cross-support beam includes a web perpendicularly connected at an upper end to the attachment flange, and a stiffening flange at a web lower end. Both the web and the stiffening flange are freely suspended within the U-shaped aperture of the T-shaped support. When joined, the cross-support beam seats on the T-shaped support allowing both the cross-support beam and the deck support beam to develop maximum bending moments at a reduced structural weight.
