34.13.2. Challenges in Design

Try these first

1. 1.

   What are irregularities in structural design?

   Hint

   Think about differences in the shape of a building.

2. 2.

   What does ductility in a structure refer to?

   Hint

   Consider how a structure behaves under stress.

3. 3.

   What is the primary challenge presented by structural irregularities?

   • They cause structural failure
   • They lead to complex dynamic behavior
   • They are easy to design against

   Hint

   Think about how unpredictability can affect design.

4. 4.

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

   • True
   • False

   Hint

   What happens to flexible materials in stress scenarios?

5. 5.

   A building has irregularities with varying floor heights and stiffness. What design strategies can be employed to ensure its earthquake resilience?

   Hint

   Think about maintaining uniform structural behavior.

6. 6.

   Explain the advantages and disadvantages of using dynamic response spectrum analysis versus time history analysis for a complex irregular structure.

   Hint

   Consider the trade-offs between detail and simplicity.
