Metal bridging is placed at the center of spans over 10 feet and where the joists pass over the girder. Determine the number of pieces of metal bridging needed for the floor in Figure 14.61.
What will be an ideal response?
Metal bridging is not needed in the joist between the center of the building and the header at the opening. Thirty pairs are needed in the top half of the drawing, 30 pairs are needed over the girder, and 24 pairs (30 – 6) are needed in the bottom half of the drawing.
Number = 2 × (30 + 30 + 24) = 168 each
