39.10. Advanced Approaches

Try these first

1. 1.

   What does PBSD stand for?

   Hint

   Think about what the focus of seismic design should be.

2. 2.

   Name one type of nonlinear analysis.

   Hint

   It helps us see how structures behave under loads.

3. 3.

   What is the main focus of Performance-Based Seismic Design?

   • To withstand maximum forces
   • To achieve specific performance levels during seismic events
   • To minimize construction costs

   Hint

   Think about goals of safety and functionality.

4. 4.

   True or False: Nonlinear Analysis Tools assume a proportional structure response to loads.

   • True
   • False

   Hint

   Consider what happens when materials yield.

5. 5.

   Analyze how an RC structure designed under PBSD principles would perform under a strong earthquake compared to traditional designs. Discuss the implications for safety and building longevity.

   Hint

   Consider the different goals of PBSD versus traditional designs.

6. 6.

   Calculate the expected performance level of a building equipped with base isolators when subjected to both low and high seismic forces. Include a discussion of the expected energy dissipation.

   Hint

   Think about how isolators change the motion experienced by the building.
