Question 1.
Define base shear in the context of seismic design.
Show hintHide hint
It relates to the weight of the building.
Question 2.
What does ductility refer to?
Show hintHide hint
Think about how materials react under stress.
3Question 3.
What does the design base shear (V) represent in structural design?
- Total gravity load
- Horizontal seismic load
- Vertical seismic load
Show hintHide hint
Think about what forces act horizontally during an earthquake.
4Question 4.
Ductility demand indicates how much deformation a structure can tolerate.
- True
- False
Show hintHide hint
This is crucial in earthquake engineering.
Question 5.
A building has a weight of 800 kN and is located in a high seismic hazard zone, yielding an A_h of 0.3. Calculate the design base shear and discuss implications.
Show hintHide hint
Use the base shear formula and reflect on the design importance.
Question 6.
You are provided with a ductility demand of 3. If the yielding force of a structure is 100 kN, what maximum displacement can the structure handle without collapsing?
Show hintHide hint
Remember how to manipulate the ductility expression.
