Challenge Problems
Push your limits with advanced challenges
A new bridge design requires computation of spectral acceleration. Given the site conditions of sandy soil and a span of 250 meters, outline the steps you would take to ensure accurate Sa calculation.
💡 Hint: Think about how each factor interacts in seismic contexts.
Evaluate how an increase in damping ratio from 5% to 15% would affect the spectral acceleration for a newly constructed tower. Provide calculations to support your analysis.
💡 Hint: Consider the relationship between damping and spectral acceleration quantitatively.
