Reinforced Tank Design- The Slab - Structural engineering

Sep 17,2003 mechanically anchored flat bottom tanks integral reinforcing pad#0183;Reinforced Tank Design- The Slab As a flat bottomed tank has essentially zero stiffness in its bottom plate,all resistance to bending must come from the foundation.The internal pressure tends to lift the shell,which must be resisted by the anchor bolts.So essentially,you have an increased uniform load over the tank bottom,with PROCESS FABRICATORS LUu)Vertical Storage Tanks Flat Bottom Builtfor storage of liquid products in bulk.Our flat bottom,cone roof tanks are ex- tremely durable and exceed U.L.Stan- dard 142 in strength,corrosion resistance,and appearance.Costly footings and pier forming are eliminated; only a con- crete slab or compacted aggregate base is required.Full text of Design Of Liquid Containing Concrete C = 0.44N = 0.44 a C.= 0.64 = 0.64 Using Section 1634.3 for flat-bottom rigid tanks,V = 0.7C 1W a = 0.7 x 0.44 x 1 x 520.3 = 160.3 kips Note that W includes the weight of tank and contained liquid.As indicated in Section 3.2.2 of Chapter 3,UBC 1997 allows the use of alternate procedure such as the one given in ACI 350.3.
