Abstract
Light steel joists may be spaced 24 inches o.c. under ceramic tile floors when floor bracing members are spaced at 16 inch o.c. intervals between the joists under such floors. Also made of light gauge steel, the bracing member is slotted to receive a return flange of a channel-shaped joist so that the tops of the joists and bracing members are co-planar.
