39.14. Performance-Based Design and Ductility Demands

Try these first

1. 1.

   What does the operational performance level signify?

   Hint

   Think about immediate usability.

2. 2.

   What type of analysis helps in assessing ductility?

   Hint

   What analysis helps understand structural deformation?

3. 3.

   What is the goal of Performance-Based Seismic Design?

   • To maximize energy use
   • To evaluate structure performance under seismic loads
   • To minimize construction costs

   Hint

   Focus on performance rather than costs.

4. 4.

   True or False: Ductility allows structures to absorb energy during seismic events.

   • True
   • False

   Hint

   What does ductility help in terms of energy?

5. 5.

   Design a building that needs to meet the 'Immediate Occupancy' level. What ductility considerations would you include?

   Hint

   Align your design ideas with performance levels discussed.

6. 6.

   Evaluate a building's ductility using pushover analysis. What factors could lead to inadequate performance during a seismic event?

   Hint

   Consider where energy absorption could be inadequate.
