Intze Principle for water towers A water tower built in accordance with the Intze Principle has a brick shaft on which the water tank sits. The base of the tank is fixed with a ring anchor (Ringanker) made of iron or steel, so that only vertical, not horizontal, forces are transmitted to the tower.
What are the various elements of Intze type tank?
- 1.3 Components of INTZE water tanks-
- Top dome-

Is code for Intze tank?
: 3370
Intze type tank is commonly used overhead water tank in India. These tanks are designed as per IS: 3370 i.e. Code of practice for concrete structures for storage of liquids.
What is the formula for meridional thrust in conical dome?
The horizontal component of this thrust will produce a hoop tension. 6. What is the formula for Meridional thrust of the spherical domes? T= [wR/ (1+cos?)] + [W/2?R.
What is hoop tension in water tank?
Hoop stress or circumferential stress it is in tangential direction. Axial stress parallel to the axis of the cylinder. Radial stress It is perpendicular to the symmetry axis but is coplanar.
Why do people have Intze tanks?
The purpose of the Intze Wedge is to provide an additional seal in the area of the highest water pressure. During the 1920s, this type of construction was gradually superseded by concrete dams or arched dams which were cheaper to build.
Is a water tank a 3370?
intended for storage of liquids, mainly water. The requirements applicable specifically to reinforced concrete and prestressed concrete liquid retaining structures are covered in IS 3370 (Part 2), and IS 3370 (Part 3) respectively.1.3 The criteria for design ofRCCstaging for overhead water tanks are given in IS 11682.
What are the different types of water tanks?
Different Types of Water Storage Tanks and Water Tanks Price List
| S.NO | Tank Name | Tank Type |
|---|---|---|
| 1 | Euro Tank | Overhead Tank |
| 2 | Vectus Mini Tank | Overhead Tank |
| 3 | Vectus Granito | Overhead Tank |
| 4 | Vectus Cool | Overhead Tank |
What is meridional thrust?
Meridional forces act in a longitudinal direction of a dome and increase from crown to base in magnitude. Meridional forces are due to the weight of the masonry and applied loads.
What is meridional stress?
Meridional refers to the direction along the axis of a solid of revolution, i.e., in the longitudinal direction. Meridional stresses are also called longi- tudinal stresses. Radial refers to the direction across the wall thickness along the radius of curvature.
What is hoop stress in dome?
Meridional stresses in dome are compressive throughout, whereas the hoop stress are compressive from crown to the circumferential line which remain unchanged in length and there after it develops hoop tension up to the base of the dome.
What is meant by hoop tension?
Hoop stress is the stress that occurs along the pipe’s circumference when pressure is applied. Hoop stress acts perpendicular to the axial direction.Hoop stress is also referred to as tangential stress or circumferential stress.
How do you calculate water hoop tension?
Find: Hoop tension, Ht = d x h x D/2. Area of steel, Ast = d x h x D/2 ?st.
What is the formula for hoop tension?
The standard equation for hoop stress is H = PDm /2t. In this equation, H is allowable or hoop stress, the P is the pressure, t is the thickness of the pipe, and D is the diameter of the pipe.
What is staging in storage tank?
The staging is acting like a bridge between container and foundation for the transfer of loads acting on the tank. In elevated water tanks, the head requirement for distribution of water is satisfied by Adjusting the height of the staging portion.
What is the minimum steel required for the base slab in water tank?
As the slab rests on firm ground, minimum steel @ 0.3 % is provided. Thickness of slab is assumed as 150 mm.
How do you calculate water tank load?
To calculate water tank load on roof slab you just need to multiply height of water tank in 10 kN/ m2 or 1000 kg/m2, which is load of water tank per meter height & 1.1m height of 1000 ltr of water tank exerts 1100 kg/m2 load over roof slab.
Is 3370 a minimum reinforcement?
Grade of concrete is taken as M30, as minimum grade of concrete for RCC structures is M30 as per IS: 3370 (Part1) 2009.
Effects on Intz Type Tank with Code Revision of IS:3370 (1965) to (2009)
| IS : 3370 -1965 | IS : 3370-2009 |
|---|---|
| 3. 0.2 % for section of thickness > 450mm | B ) The minimum reinforcement can be further reduced to |
| 1. 0.24 % for HYSD bars. |
How many part of is 3370?
Part 2
Abstract. IS 3370 (Part 2): 2009 which covers the ‘Recommendations for design of concrete structure for storage of liquid’ was published in 1965. The code was split into four parts.
Is 3370 revised?
All four parts of IS 3370 are revised. A new part to deal with construction practices, quality management and maintenance is required.
