Waffle roof structure.

We will start by first modeling the waffle structure entirely in rhino showing how it is less forgiving of design changes as it requires a complete manual re creation of the ribs of the structure every time a change is made. The waffle system has a few components that define the strut labels and has a slider to control the label size to keep the model organized. This structure was designed to be more solid when used on longer spans and with heavier loads. Figure 3 shows the massing model of a canopy design the top of which we want to construct as a waffle structure.

Waffle slab or ribbed slab is a structural component which is plain on its top and contains grid like system on its bottom surface. A 120 mm thick slab with a minimum rib thickness of 125 mm for continuous ribs is required to achieve a 2 hour fire rating.

The grid is formed by the removal of molds after the concrete sets. Finally the definition orients the strut curves to the x y axis so that the curves can be easily output directly to a cnc mill or laser cutter.

Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab.

The top of ribbed slab is normally thin and the bottom grid lines are generally ribs which are laid perpendicular to each other with equal depth.
