Tank means a container,consisting of a shell and heads,that forms a pressure tight vessel having openings designed to accept pressure tight fittings or closures,but excludes any appurtenances,reinforcements,fittings,or closures.Test pressure means the pressure to which a tank is subjected to determine structural integrity.360R-06 Design of Slabs-on-Ground - NICFIThe primary purpose of the reinforcement is to limit the width of any cracks that may form between the joints.Bar or wire reinforcement should be stiff enough so that it can be accurately located in the upper 1/3 of the slab.Slabs may be reinforced with reinforcing bars,welded wire reinforcement sheets,steel fibers,or macropolymeric fibers.360R-06 Design of Slabs-on-Ground - NICFI7.3Reinforcement for crack-width control only 7.4Reinforcement for moment capacity 7.5Reinforcement location Chapter 8Design of shrinkage-compensating concrete slabs,p.360R-32 8.1Introduction 8.2Thickness determination 8.3Reinforcement 8.4Other considerations Chapter 9Design of post-tensioned slabs-on-ground,p.360R-36
