摘要： A beam can comprise a plurality of steel channel members that extend along a longitudinal axis. The plurality of steel channel members can cooperate to define an interior volume that is configured to receive concrete therein. The plurality of steel channel members can comprise a first C-shaped channel member defining a channel therein and having first and second flanges. The channel of the first C-shaped channel member can define a portion of an outer boundary of the interior volume. The first and second flanges can extend into the interior volume. A plurality of internally projecting members can be spaced along the longitudinal axis. The plurality of internally projecting members can extend into the interior volume from a steel channel member of the plurality of steel channel members. A strap can extend across the interior volume so that when the interior volume is filled with concrete, the strap engages the concrete.
