Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does an increase in damping typically do to base shear values?
- Increase base shear
- Decrease base shear
- No effect
💡 Hint: Think about the relationship between damping and spectral acceleration.
Question 2
True or False: Base shear is only determined by the weight of the structure.
- True
- False
💡 Hint: Consider what affects seismic forces.

Challenge Problems
Push your limits with challenges.
Question 1
A new building weighs 2000 kN and has a damping ratio of 25%. Calculate the expected base shear if the seismic coefficient for its location is determined to be 0.12. What design strategies should you keep in mind to further reduce seismic forces?
💡 Hint: Focus on the relationship between damping and seismic responses.
Question 2
If increasing the damping of a structure from 10% to 30% reduces its base shear from 300 kN to a new value, calculate the reduction in kN and percentage decrease in base shear.
💡 Hint: Calculate both the actual kN reduction and then the percentage based on initial values.
