Challenge Problems
Push your limits with advanced challenges
A newly designed bridge is expected to experience a PGA of 0.4g. Explain the considerations engineers should take for ensuring safety against potential PGV and PGD.
💡 Hint: Consider how forces affect movement differently in rigid versus flexible designs.
In a proposed high-rise building, the potential PGV measured is 20 cm/s. Discuss the implications for design choices compared to a structure where PGA is the main factor.
💡 Hint: Relate movement and flexibility to height and design impacts of high rises.
