Challenge Problems
Push your limits with advanced challenges
A school building designed with a 5% damping ratio shows spectral acceleration of 1.0g during a simulated earthquake. If the damping ratio is increased to 10%, what can you estimate will happen to the spectral acceleration and why?
💡 Hint: Think about how energy absorption changes.
In a seismic analysis, a building's response spectrum shows an increasing trend in spectral acceleration as damping decreases. At what damping ratio would you expect to see diminishing returns in terms of spectral acceleration?
💡 Hint: Consider extremely low resistance to vibrations.
