What are the factors to be considered when designing a retaining wall?

What are the factors to be considered when designing a retaining wall?

When designing a retaining wall, there are seven factors to consider: materials, type of wall, design or on-site placement, drainage, foundations, cant or batter, and anchors or “deadmen”.

What are the special design considerations for the water retaining structures?

Concrete water retaining structures are considered as essential facilities that require special care and accuracy in their design. In these structures, crack and leakage control are of prime design considerations. For this reason, serviceability becomes the major factor in the design.

How do you design a retaining wall?

Designing Retaining Walls

1. Select the retaining wall location. Minimize soil excavation and backfill.
2. Determine retaining wall height and geometry. Calculate the retaining wall height at its tallest position.
3. Evaluate structural requirements.
4. Calculate the total wall structure.

What are the water retaining structures?

The retaining structures used to build reservoirs are called dams and dikes. A dam is built on the riverbed; it serves to hold back water and raise the water level of the resulting reservoir.

Do retaining walls need building regulations?

Independent, freestanding retaining walls may not require building regulation approval; however, any structures must be structurally sound and well maintained. Where a retaining wall is near to a boundary, it may be subject to the provisions of the Party Wall Act, and may be required to continue a right of support.

When designing a water storage tank should movement joints be installed?

When one designs a concrete water storage tank, it’s essential to install movement joints to control the movement due to variation of temperature, shrinkage and hydration temperature drop etc.

Is code for design of water retaining structures?

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.

What are the design criteria to be satisfied for the stability of a gravity retaining wall?

Factor of Safety – For stability, a retaining wall should satisfy the following conditions. The wall should be stable against sliding. The factor of safety against sliding shall be a minimum of 1.5. The Wall should be stable against overturning.

What is the principle of designing a gravity retaining wall?

1. Stability against Overturning: The wall must be safe against overturning. Overturning is caused by the horizontal component of the resultant active earth pressure, Pa, in the form of an overturning moment, ΣMo, about the toe of the wall.

What is the is code used in design of water retaining structure?

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.

Is a retaining wall considered a structure?

A retaining wall is a strong structure that is made to keep a hill, slope or mound of earth in place. Due to the weight of the earth behind the wall, a retaining structure must adhere to high construction standards.

What are the requirements for a water retaining structure?

Design of Water Retaining Structures The design of water retaining structures is carried out in accordance with BS 8007. Crack width is the limiting criteria in this design. Generally, the concrete structures are designed to the maximum crack width of 0.3mm.

What should I consider when designing a retaining wall?

What should I consider when designing a retaining wall? When designing a retaining wall, there are seven factors to consider: materials, type of wall, design or on-site placement, drainage, foundations, cant or batter, and anchors or “deadmen”. What materials should I choose?

Which is the best grade for retaining structures?

The 35A concrete grade is used for the water retaining structures which is expected to have a high durability while keeping the strength as Grade 35. Locations of construction joints are facilitating path for water penetration. Minimizing the construction joints is an important consideration for water retaining structures.

How are movement joints installed in water storage tanks?

In designing water storage tanks, movement joints can be installed in parallel with steel reinforcement.
