Design a circular overhead water tank of 200 kL capacity overa staging of 25 m.Assume suitable propertions and prepare detailed structural drawings.
What does "overa staging" mean ? What "propertions" are you talking about?
What kind of help do you need?
Is the water tank in RC? Most water tanks in North America are in steel and supported over steel columns, which also gives resilliance when subject to earthquakes.
200kL is basically 200 m³. It could be a cylinder of 6.5m diameter by 6m high.
Be sure to include deadloads, earthquake and wind loads in your calculations. You will need to investigate resonance frequencies and dynamic behaviour under earthquake loads.
Also, include bracing and check buckling for the columns according to the l/r ratios. 25 is quite long.
Designing a circular overhead water tank requires a step-by-step approach. Here's an outline explaining how to get started on the detailed structural drawings:
1. Determine the tank capacity: The given capacity is 200 kL (kiloliters).
2. Calculate the tank diameter: The tank's capacity and shape (circular) will influence the tank's dimensions. Use the formula:
Tank volume = π * (Diameter)^2 * Height
Rearrange the formula to solve for the diameter:
Diameter = √(Tank volume / (π * Height))
Substituting the values given:
Diameter = √(200000 / (π * 25)) ≈ √(3200) ≈ 56.57 m
3. Calculate the tank height: Rearrange the tank volume formula to solve the height:
Height = Tank volume / (π * (Diameter)^2)
Substituting the values given:
Height = 200000 / (π * (56.57)^2) ≈ 62.83 m
Note: You should adjust the dimensions to be practical and suitable for construction purposes. Ensure the diameter and height values are compatible with standard construction practices, considering factors like material thickness, reinforcement requirements, etc.
4. Determine the tank wall thickness: The wall thickness depends on various factors like material strength, load conditions, safety factors, etc. A structural engineer or designer should perform calculations based on these factors to determine the appropriate wall thickness.
5. Prepare detailed structural drawings: Once you have the tank dimensions, you can create detailed structural drawings. The drawings should include the following aspects:
- Plan view showing the tanks' circular shape, diameter, wall thickness, and inlet/outlet locations.
- Elevation view highlighting the vertical height, overall dimensions, and any support structures.
- Cross-sectional views detailing the tank wall thickness, reinforcement details, and any additional structural elements like columns or braces.
- Any necessary details describing the connections between the tank and staging structure.
It is crucial to involve a structural engineer or designer who can ensure the design meets safety standards and consider local building codes and regulations.
