Design of Slabs on Grade
We are in the process of designing a large warehouse with both Forklift traffic and heavy post loads from pallet storage systems.
We have a initial thickness design of the concrete slab following the methods outlined in PCA publication “Slab Thickness Design for Industrial Concrete Floors on Grade” as well as WRI Charts as used in Ringo/Anderson’s Book “Designing Floor Slabs on Grade”. These elastic methods give slab thicknesses in the range of 10 + inches.
Peter Higgins cited an article by Shentu “Load-Carrying Capacity for Concrete Slabs on Grade” (ASCE Journal of Structural Engineers 1997), that results in thinner slabs (Less then 8 inches), however I have NOT been able to find any reference to the usage of this method in design practice. The current ACI Report on “Design of Slabs-on-Ground” ACI 360R-06 (2006 publication) does NOT reference this ultimate, non-elastic method.
My question is, there anyone using a method other then the conventional PCA or WRI methods to size Slabs-on-Grade for Storage Rack Post Loads, and if so what is their basis and background.
Advise and guidance is welcomed on this matter.
