Question 1.
What is the primary function of a strong column in a seismic design?
Show hintHide hint
Think about the relationship between beams and columns.
Question 2.
Define ductility in the context of structural engineering.
Show hintHide hint
Consider how materials behave under stress.
3Question 3.
What is the primary principle of the Strong Column - Weak Beam concept?
- Columns should fail first
- Beams should yield first
- Both should fail simultaneously
Show hintHide hint
Remember the relationships of moment resistance.
4Question 4.
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
Show hintHide hint
Revisit the definitions of the equation.
Question 5.
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.
Show hintHide hint
Agree upon the laws governing moment resistance.
Question 6.
Discuss the implications of ignoring the Strong Column - Weak Beam design philosophy in a high-rise building situated in a high seismic zone.
Show hintHide hint
Consider both structural integrity and safety.
