Preliminary proportioning of counterfort retaining wall CE6601 Notes:
1. Thickness of heel slab and stem = 5% of Height of wall
2. Thickness of toe slab [buttress not provided] = 8% of Height of wall
3. Thickness of counterfort = 6% of height of wall
4. In no case thickness of any component be less than 300mm.
5. Spacing of counterforts = 1/3rd to 1/2 of Height of wall
6. Each panel of stem and heel slab are designed as two way slab with one edge free (one way continuous slab).
7. The toe slab is designed as
a. Cantilever slab when buttress is not provided
b. One way continuous slab, when buttress is provided
8. Counterfort is a triangular shaped structure designed similar to a T-Beam as vertical cantilever with varying depth (stem acts as flange).
The main reinforcement is along the sloping side. Stirrups are provided in the counterfort to secure them firmly with the stem. Additional ties are provided to securely tie the counterfort to the heel slab.
Water pressure distribution CE6601 Notes:
1. On side walls, it acts linearly varying from 0 at top to ‘wh’ at bottiom.
2. On base slab, uniform pressure acts with intensity ‘wh’
The method of design adopted for design of water tank is working stress method.
The permissible stress values in concrete and steel are given in Tables 21 and 22 of IS456- 2000.
