40.18.2. Ground Supported Water Tanks

Try these first

1. 1.

   What is sloshing in the context of water tanks?

   Hint

   Think about how water behaves when shaken.

2. 2.

   Define base shear.

   Hint

   Consider it as the pushing force acting from the ground.

3. 3.

   What is sloshing in ground-supported water tanks?

   • Movement of water
   • Foundation issue
   • Slip failure
   • Material deterioration

   Hint

   Think about how water can behave when a tank shakes.

4. 4.

   Base shear is calculated as which of the following?

   • Weight of walls
   • Water pressure
   • Lateral force at base
   • Internal pressure

   Hint

   Remember that it's related to the forces acting on the tank's base.

5. 5.

   Design a ground-supported water tank for a seismic zone with a base shear of 100 kN. What considerations must you factor in during the design?

   Hint

   Reference your understanding of seismic design principles.

6. 6.

   Given a tank with a height of 5m and a diameter of 3m, calculate the maximum slosh height during a quake with a peak ground acceleration of 0.3g.

   Hint

   Look for common empirical models used for slosh calculations.
