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 鈥淪lab thickness design for industrial concrete floors on grade鈥?nbsp; as well as wri  charts as used in ringo/anderson鈥檚 book 鈥淒esigning floor slabs on grade鈥?  these elastic methods give slab thicknesses in the range of 10 + inches.
peter higgins cited an article by shentu 鈥淟oad-carrying capacity for concrete slabs on grade鈥?(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 鈥淒esign of slabs-on-ground鈥?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.
