The inspection port is the large opening at the top of most storage containers.It allows the user or maintenance provider access to the inside of the tank (remember Safety regarding tanks).In many RWH systems,this inspection port is used as the inlet of the tank,and there are basket screens which fit perfectly into these openings.Design of Steel Tanks - The ConstructorA rectangular steel tank is shown in Fig.The rectangular steel tanks are made of steel plates with flat bottom.The widths of steel plates generally adopted are 1.20 m,1.25 m and 1.30 m depending upon availability of the plates.the thickness of steel plates should not be less than 6 mm.DESIGN RECOMMENDATION FOR STORAGE TANKSuplifting tank and the plastic deformation of the bottom plate at the shell-to-bottom juncture in the event of earthquake,the design spectrum for sloshing in tanks,the design pressure for silos,and the design methods for the under-ground storage tanks as well.

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
