33.4.1. Elastic Response Spectrum

Try these first

1. 1.

   What is the Elastic Response Spectrum based on?

   Hint

   Think about structural behavior during earthquakes.

2. 2.

   Name one response parameter in the Elastic Response Spectrum.

   Hint

   What are the three ways a structure might move?

3. 3.

   What does the Elastic Response Spectrum assume about structural behavior?

   • It assumes nonlinear behavior
   • It assumes linear behavior
   • It assumes only static loads

   Hint

   Think about how structures respond during an earthquake.

4. 4.

   True or False: The natural period directly affects how buildings respond to earthquakes.

   • True
   • False

   Hint

   Consider what affects the way buildings sway.

5. 5.

   Consider a new high-rise building with a natural period of 1.5 seconds. If the damping is increased from 2% to 10%, discuss the expected effects on the Elastic Response Spectrum.

   Hint

   Focus on how damping influences building response.

6. 6.

   Design a hypothetical scenario where an Elastic Response Spectrum would differ for two structures: a skyscraper and a low-rise building. What differences in parameters would you expect?

   Hint

   Think about how building height and response times interact.
