Structural member assemblies, beams, and support structures comprising same

A beam having an upper surface and comprising:

• a plurality of steel channel members that extend along a longitudinal axis, the plurality of steel channel members comprising:
• first and second channel members spaced along a transverse axis;
• and
• a bridge channel member extending between, and coupled to, the first and second channel members,
• wherein the plurality of steel channel members cooperate to define an interior volume that is configured to receive concrete therein,
• wherein the first and second channel members comprise opposed respective outer surfaces, wherein the first and second channel members each define a channel and a channel opening extending along the channel, wherein the opposed respective outer surfaces at least partly define the interior volume, wherein the respective channel openings of the first and second channel members face outwardly from the interior volume;
• a plurality of straps secured to upper surfaces defined by the first and second channel members, wherein each strap of the plurality of straps extends across the interior volume;
• and
• sing a plurality of depending internally projecting components attached to, and extending downwardly from, the plurality of straps, wherein the plurality of depending internally projecting components are positioned between and spaced from the upper surfaces of the first and second channel members.

A system comprising:

• a beam having an upper surface and comprising:
• a plurality of steel channel members that extend along a longitudinal axis, the plurality of steel channel members comprising:
• first and second channel members spaced along a transverse axis;
• and
• a bridge channel member extending between, and coupled to, the first and second channel members, wherein the bridge channel member comprises:
• a base wall;
• first and second side walls extending perpendicularly from the base wall;
• and
• first and second flanges respectively inwardly extending from the first and second side walls,
• wherein the plurality of steel channel members cooperate to define an interior volume that is configured to receive concrete therein
• wherein the first and second channel members comprise opposed respective outer surfaces, wherein the first and second channel members each define a channel and a channel opening extending along the channel, wherein the opposed respective outer surfaces at least partly define the interior volume, wherein the respective channel openings of the first and second channel members face outwardly from the interior volume;
• and
• a plurality of inwardly projecting members coupled to and extending upwardly from the base wall;
• and
• a column coupled to the beam.
