Question 1.
What does 'm' represent in the equation of motion?
Show hintHide hint
Think about it in terms of how much material is in the structure.
Question 2.
Define elastic response.
Show hintHide hint
Remember the concept of memory in materials.
3Question 3.
What does the damping ratio affect during structural response to earthquakes?
- It reduces mass
- It increases stiffness
- It affects peak response
Show hintHide hint
Think about how shock absorbers work in a car.
4Question 4.
True or False: An inelastic response leads to permanent deformations in a structure.
- True
- False
Show hintHide hint
Think about a bent beam after a heavy load.
Question 5.
Given a mass of 500 kg and a damping ratio of 0.5 for an SDOF system with a stiffness of 20000 N/m, calculate the peak response under a sinusoidal ground motion.
Show hintHide hint
Consider how the damping affects the maximum amplitude during oscillations.
Question 6.
Discuss the implications of earthquake frequency on various structures. How would the design differ for a tall building versus a bridge?
Show hintHide hint
Think about how different structures perform under varying frequencies.
