Waffle Slab - Equivalent Average Thickness
Waffle Slab - Equivalent Average Thickness
(OP)
I have to analyze an existing waffle slab and have been looking for the correct procedure to convert my slab and ribs to an equivalent average thickness. CRSI shows a charts, but I need to do a handcalc. The formula CRSI provides has a "tr" variable, which is the equivalent thickness of the rib area. I can't give this out. Can anyone help me?

CRSI has a procedure to calculate approximate deflections by using a solid slab thickness having the computed equivalent stiffness of the waffle slab. The thickness "te" is computed as the average of the gross moment of inertias of the solid head area and ribbed area.
