Question 1.
What is ductility in structures?
Show hintHide hint
Think about flexibility under stress.
Question 2.
Define plastic hinge.
Show hintHide hint
Consider where deformation occurs during stress.
3Question 3.
What does ductility allow a structure to do during an earthquake?
- Withstand larger loads
- Absorb and dissipate energy
- Increase stiffness
Show hintHide hint
Think about how structures react under dynamic loads.
4Question 4.
True or False: Ductility demand is the maximum deformation a structure can handle.
- True
- False
Show hintHide hint
Focus on the definitions of demand versus capacity.
Question 5.
A building is constructed with ductility demand estimated at 3% deformation. Given that the designer aimed for a capacity of 2%, discuss the implications for structural safety.
Show hintHide hint
Examine what happens when demand exceeds capacity.
Question 6.
Evaluate the following structural design principles for enhancing ductility: material choice, hinge placement, and stiffness distribution. Which holds the most critical role in energy dissipation?
Show hintHide hint
Think about how each factor contributes to overall performance.
