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.

At depth of 1 m.

Design of bottom slab. As the soil is saturated, the angle of friction of submerged soil will be low. Hence values of P0 and Pr can be calculated. Design of liquid retaining structures is different from ordinary R. By completing the triangle of moments, the moments, the moments in the braces can be or.

View Contact Call Seller Now. Roofs i Provision of Movement Joints. Design of Roof Slab. The wind force acting on the tank and staging produces tension on the windward side columns and compression on the leeward side columns. Pressure of submerged earth and water at depth of 4. Knowing equation of elastic curve, values of P0 and Pr can be calculated. Maximum hoop tension occurs at 0. Efficient compaction preferably by vibration is essential.


In case of tanks intended for the storage of water for domestic purpose, the roof must be made water-tight. Direct tension on short wall is w H-h. For calculation of weight of water center line dimensions are taken as while calculating load on beams centre line dimensions were taken.

There are three types of movement joints. This type of joint is provided between wall and floor in some wwter tank designs.

Elevated tanks are supported on staging r.c.c.ovdrhead may consist of masonry walls, R. All joints should be made water-tight as these are potential sources of leakage. In such cases the vertical component of the force to each column is found as given above. The side walls will serve as girders.

Pressure of Saturated soil acting from outside and no water pressure from inside. A typical joint is shown in Fig. No upward load is produced in column when tank empty. We were selected as Consultants for the design of the overhead tank through competitive bidding for tan, projects. In strength calculations the permissible concrete stresses shall be in accordance with Table 1. Let ‘t’ be thickness of wall. For small capacities rectangular tanks are generally used and for bigger capacities circular tanks are used.


Warer the ratio of length to breadth of slab is greater than 2, slab will span in shorter direction. Effective depth required Design of beam B2.

Overhead RCC Water Tanks Construction

Approximate method of design of circular tanks with fixed base. Walls i Provision of Joints a Sliding joints at the base of the wall. In normal circumstances the screed layer shall be of grade not weaker than Mwhere injurious soils or aggressive water are expected, the screed layer shall be of grade not weaker than M and if necessary a desihn resisting or other special cement should be used.

Design of short wall 1. In addition to bending, walls are subjected to direct tension caused by the hydrostatic pressure on the walls.

For foundation concrete mix of M is used. Steel reinforcement is provided for B.

At bottom, slope and deflection will be zero.
