DESIGN OF R.C.C. OVER HEAD TANK - MAIN PROJECT REPORT

Oct 29, 2026

Storage reservoirs and overhead tanks are used to store water and similar liquids such as petroleum products. Force analysis is treated as largely independent of the chemical nature of the stored product. Tanks are designed as crack-free structures to prevent leakage. The report outlines the theory for designing an elevated circular water tank with domed roof and conical base using the working stress method, while elements are designed using the limit state method.

DESIGN OF R.C.C. OVER HEAD TANK MAIN PROJECT REPORT Submitted in partial fulfilment of the Requirements for the award of the degree of Bachelor of Technology In Civil Engineering By G.HEMALATHA J.TEJASWI (09245A0105) (09245A0106) Under the esteemed guidance of MR.MALLIKARJUN REDDY Assistant professor of Civil Engineering Department Department of Civil Engineering Gokaraju Rangaraju Institute of Engineering and Technology (Affiliated to JNTU) Hyderabad 2012 DESIGN OF R.C.C OVERHEAD TANK ABSTRACT Storage reservoirs and overhead tank are used to store water, liquid petroleum, petroleum products and similar liquids. The force analysis of the reservoirs or tanks is about the same irrespective of the chemical nature of the product. All tanks are designed as crack free structures to eliminate any leakage. This project gives in brief, the theory behind the design of liquid retaining structure (Elevated circular water tank with domed roof and conical base) using working stress method. Elements are design in limit state method. ACKNOWLEDGEMENTS I would like to express my gratitude to all the people behind the screen who helped me to transform an idea into a real application. I would like to express my heart-felt gratitude to my parents without whom I would not have been privileged to achieve and fulfill my dreams. Iam grateful to our principal, Mr. Jandyala N.Murthi who most ably run the institution and has had the major hand in enabling me to do my project. I profoundly thank Mr. G.Venkataramana, Head of the Department of CIVIL Engineering who has been an excellent guide and also a great source of inspiration to my work. I would like to thank my internal guide Mr. V.Mallikarjun reddy Asst.Professor for his technical guidance, constant encouragement and support in carrying out my project at college. The satisfaction and euphoria that accompany the successful completion of the task would be great but incomplete without the mention of the people who made it possible with their constant guidance and encouragement crowns all the efforts with success. In this context, I would like thank all the other staff members, both teaching and non-teaching, who have extended their timely help and eased my task. G.Hemalatha 09245A0105 J.

FAQs

What is the purpose of designing elevated water tanks and overhead tanks?

They are used to store water and other liquids such as petroleum and petroleum products. The design goal is to store these liquids safely without leakage.

Which design approaches are discussed in the report?

The theory is presented using the working stress method, while structural elements are designed using the limit state method.

Why are R.C.C. tanks designed as crack-free structures?

Crack-free design is intended to eliminate leakage. This ensures the tank functions safely as a liquid-retaining structure.
