Creating a roof structure duration. Waffle slab or ribbed slab is a structural component which is plain on its top and contains grid like system on its bottom surface. This form of construction is not very common because of the formwork costs and the low fire rating. 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.

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 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. Figure 3 shows the massing model of a canopy design the top of which we want to construct as a waffle structure. Grasshopper 006 waffle structure beams concept fabrication duration.

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 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. Jammy chong 267 876 views.

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.

A waffle slab is flat on top while joists create a grid like surface on the bottom.
