33.10.1. Seismic Load Calculation

Try these first

1. 1.

   What does the term 'base shear' refer to?

   Hint

   Think about the forces acting at the base of a building.

2. 2.

   What is 'spectral acceleration'?

   Hint

   It involves acceleration during an earthquake.

3. 3.

   What does 'V' represent in the seismic load calculation formula?

   • Base Shear
   • Spectral Acceleration
   • Seismic Weight

   Hint

   Recall the formula you learned.

4. 4.

   Is the response modification factor (R) used to increase the seismic demands on structures?

   • True
   • False

   Hint

   Think about how it affects the forces experienced by the structure.

5. 5.

   A building weighing 2500 kN experiences a spectral acceleration of 0.4g. If the response modification factor is 6, what is the base shear? Detailed calculations are required.

   Hint

   Use the provided formula and methodically break down your calculations.

6. 6.

   Consider a structure with a seismic weight of 1800 kN and a spectral acceleration of 0.35g. If the structure has a response modification factor of 3, compute the base shear. Provide step-by-step reasoning.

   Hint

   Apply the formula while considering the significant variables.
