Challenge Problems

Push your limits with challenges.

Question 1

A new base-isolated building design anticipates a damping ratio of 15%. Calculate the expected spectral acceleration given a standard response spectrum for 5%. What impact does this have on the design?

💡 Hint: Refer to the reduction factor table provided in the chapter.

Question 2

Evaluate the effects of installing energy dissipation devices on a multi-storey structure's behavior during an earthquake. What calculations must be performed to reassess the design?

💡 Hint: Consider how energy absorbed impacts the overall forces experienced by the structure.
