32.11. Pushover Analysis and Capacity Spectrum Method

Try these first

1. 1.

   What is pushover analysis?

   Hint

   Think about how structural engineers test buildings.

2. 2.

   Define capacity curve.

   Hint

   What key parameters are being compared?

3. 3.

   What is the primary function of pushover analysis?

   • To test structural material
   • To assess seismic performance
   • To calculate wind load

   Hint

   Consider which forces the analysis is concerned with.

4. 4.

   True or False: The capacity curve may change as the structure is pushed to failure.

   • True
   • False

   Hint

   Think about how structures degrade over time.

5. 5.

   Analyze a hypothetical mid-rise building subjected to pushover analysis. Describe how you would construct the capacity curve, and what data you would need for proper evaluation.

   Hint

   Consider how you would gather data during loading.

6. 6.

   Given the limitations of pushover analysis, propose an alternative analysis method for a tall structure and justify your choice.

   Hint

   Think about dynamic versus static methods.
