Abstract:
In our previous article The First Commandment for Floor Slabs: Thou Shalt Not Curl Nor Crack...(Hopefully) (Concrete International, January 1999), we discussed some important concepts concerning the design of slabs-on-ground such as curling, linear shrinkage, joint spacing, and serviceability issues. Using these concepts we have developed design aids for slabs-on-ground that are unreinforced or have a small amount of reinforcing that is not included in the structural capacity, which are covered in this article. We have used these design aids for many years to design numerous high quality industrial slabs. Design graphs presented here for joint spacings, uniform loads, rack loads, and lift truck loads help make the design of unreinforced slabs much simpler and easier; furthermore, these design aids usually provide more economical slabs than those designed by more traditional methods.
