Question 1.
What is a design code?
Show hintHide hint
Think of it as a rulebook for engineers.
Question 2.
Name one example of a dynamic load.
Show hintHide hint
Consider loads that vary over time.
3Question 3.
What does the Response Reduction Factor (R) account for?
- Load magnitudes
- Energy dissipation inelastic behavior
- Moment of inertia
Show hintHide hint
Think about energy during an earthquake.
4Question 4.
True or False: Each structure has only one natural frequency.
- True
- False
Show hintHide hint
Consider how different parts can vibrate uniquely.
Question 5.
Calculate the required base shear for a building designed for seismic load using a Response Reduction Factor of 3 and a static base shear of 240 kN.
Show hintHide hint
Remember the purpose of the Response Reduction Factor.
Question 6.
Consider a building’s natural frequency is 2 Hz, and its structure is dynamically loading during ground shaking of 3Hz. What approach could be taken to avoid resonance?
Show hintHide hint
Consider devices that alter vibration responses.
