This project gives in brief, the theory behind the design of liquid retaining structure (Elevated circular water tank with domed roof and conical base). and further guidance on seismic design methods for storage tanks larger tanks, and as such the seismic design for these larger storage tanks.

A gap is sometimes left temporarily between the concrete of adjoining parts of a structure which Fig. These conditions will give two equations. Direct tension on short wall is w H-h. Additionally it should be ensured that tensile stress on the liquid retaining face of the equivalent concrete section does not exceed the permissible tensile strength of concrete as given in table 1.

Steel in Vertical Span x For -ve B. Shear taken by two r.c.c.ovrhead of 32 oof. The section will be safe as depth provided is quite considerable. In case length of structure is large it should be subdivided into suitable lengths separated by movement joints, specially where sections are changed the movement joints should be provided.

Load in the top portion is taken by the hoop tension caused in the top portion. Direct tension in long walls.

Overhead RCC Water Tanks Construction

Stresses due to drying Shrinkage or Temperature Change. Joints in Liquid Retaining Structures. Water pressure acting from inside and no earth pressure acting from outside. Bottom one metre acts as cantilever and remaining 3 m acts as slab supported on long walls.

Assume thickness of roof slab as 15 cm. Other causes of leakage in concrete are defects such as segregation and honey combing. In case the length of tank is more than twice the breadth of the tank, the slab is designed edsign spanning along the shorter span.

Get best deals for coconut. The tank is covered at top.

Sher stress is negligible. The design principles of underground tanks are same as for tanks r.c.c.overhear on the ground. Meridional thrust per 1 cm.

These four equations can be solved for four constant. Let Ath be the reinforcement required at depth h. Depth of 4 m, is provided with free board of 20 cm. As the bending moment is proportional to the depth of water, reinforcement will vary linearly with depth of water. Maximum g.c.c.overhead ve B. At top the shear force and B.

Rise of 1 m. Circular Tanks Fixed at Base and Free at top. Thickness of 10 cm. The joint is shown in Fig. And we are proud to be the one of the best people in the field of civil engineering. This will be taken by wall and the distribution steel provided. Rectangular tanks are provided when r.c.cc.overhead capacity tanks are required.

If the tank is covered at the top the vertical walls are considered to be supported at the top. Steel required for – ve B. In such a case triangle of moments will be right angled triangle and side Desiggn will be hypotenuse. Waater mix used is M Table 3C gives coefficients for ring tension and B.

For large tanks base slab is supported on series of beams supported on columns. Design of bottom one metre B.
