Challenge Problems
Push your limits with challenges.
Question 1
A building has a damping ratio of 8%. Calculate its Damping Modification Factor using Eurocode 8.
💡 Hint: Substitute and simplify to find the square root.
Question 2
If a structure experiences an increase in damping ratio from 5% to 25%, how does this impact the required base shear during a seismic event?
💡 Hint: Calculate η(25) first to assess its impact on forces.
