Challenge Problems
Push your limits with advanced challenges
You are an engineer evaluating a structure on soft soil. Discuss the challenges you may face regarding its natural frequency and response to seismic activity.
💡 Hint: Consider past earthquake examples where structures failed due to poor soil assessments.
Calculate the change in natural period for a given structure as it moves from a hard foundation to various types of soils (e.g., soft clay, dense sand). Discuss the implications.
💡 Hint: Use the relationship between stiffness and natural period adjusted for each soil type.
