4.10. Practical Implications in Structural Design

Try these first

1. 1.

   What is a design code?

   Hint

   Think of it as a rulebook for engineers.

2. 2.

   Name one example of a dynamic load.

   Hint

   Consider loads that vary over time.

3. 3.

   What does the Response Reduction Factor (R) account for?

   • Load magnitudes
   • Energy dissipation inelastic behavior
   • Moment of inertia

   Hint

   Think about energy during an earthquake.

4. 4.

   True or False: Each structure has only one natural frequency.

   • True
   • False

   Hint

   Consider how different parts can vibrate uniquely.

5. 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.

   Hint

   Remember the purpose of the Response Reduction Factor.

6. 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?

   Hint

   Consider devices that alter vibration responses.
