Question 1

What is the formula for estimating the natural period of RC moment-resisting frame buildings according to IS code?

  • T = 0.075h^0.75
  • T = 0.085h^0.75
  • T = h^0.75

💡 Hint: What kind of frame does the formula pertain to?

Question 2

True or False: The natural period is irrelevant when calculating seismic forces.

  • True
  • False

💡 Hint: Consider how buildings behave during an earthquake.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
