Question 1

What is the primary principle of the Strong Column - Weak Beam concept?

  • Columns should fail first
  • Beams should yield first
  • Both should fail simultaneously

💡 Hint: Remember the relationships of moment resistance.

Question 2

True or False: The equation \( \sum M_c \geq 1.2 \times \sum M_b \) is designed to ensure that beams have a greater moment capacity than columns.

  • True
  • False

💡 Hint: Revisit the definitions of the equation.

Challenge Problems

Push your limits with challenges.

Question 1

In a design where the moment resistance of beams is calculated to be 40 kNm, what should be the minimum moment resistance for columns? Propose how you would ensure that this is maintained in practice.

💡 Hint: Agree upon the laws governing moment resistance.

Question 2

Discuss the implications of ignoring the Strong Column - Weak Beam design philosophy in a high-rise building situated in a high seismic zone.

💡 Hint: Consider both structural integrity and safety.
