Challenge Problems
Push your limits with advanced challenges
Design a hypothetical tall building in a seismic zone. Use the height of 20 meters and provide three calculations: the natural period as per IS code for RC buildings, how this period could change with different soil conditions, and the potential impact of failing to adhere to these calculations.
💡 Hint: Consider both the height and soil conditions in your calculations.
Debate the practical implications of changes to the IS code, focusing on how revisions in the period estimations could affect current buildings during retrofitting for seismic compliance.
💡 Hint: Think about why building codes are updated in response to new research.
