Designing Floor Slabs on Grade by Boyd C. Ringo, Robert B. Anderson

How thick should the slab be?
How strong should the concrete be?
Is reinforcement needed?
Where should the joints be placed?
Can adding flbers enhance the slab3 performance?
When is post-tensioning appropriate?
What can be done to control cracking?

This how-to--do-it book provides practical answers to these and other major questions that confront owners and designers when an industrial floor is needed. It is intended to simplify and improve the design of slabson grade for commercial and residential as well as industrial uses.
Design includes all of the decisions, specifications, and details made and documented before construction can begin. It is based on properties of both the subgrade support and the concrete material. The process determines thickness, any necessary reinforcement, and jointing details as well as standards for construction of the slab. The authors regard design as a two-step procedure: thickness selection is done by one of the methods listed below; then other features such as joint location and treatment and construction tolerances are determined. Even though these steps are intimately related, they are commonly thought of as two separate procedures.

Drawing on their combined experience of many decades at the forefront of slab design and construction technology, Ringo and Anderson have prepared a text designed to help professionals at many different levels of slab design expertise.
