Question 1.
What is the formula to calculate base shear?
Show hintHide hint
Remember the relationship between the seismic weight and horizontal forces.
Question 2.
In a seismic zone with a higher earthquake risk, how is the design horizontal seismic coefficient (A) affected?
Show hintHide hint
Think about how forces change with seismic levels.
3Question 3.
What does base shear (V) represent in seismic design?
- Total lateral force at the base
- Weight of the structure
- Dynamic response of the structure
Show hintHide hint
Think about what forces a building experiences during an earthquake.
4Question 4.
True or False: The design horizontal seismic coefficient is necessary for calculating base shear.
- True
- False
Show hintHide hint
Recall the formula.
Question 5.
Consider two buildings: Building A is in Zone II with a seismic weight of 400 kN and A=0.2, while Building B is in Zone IV with a seismic weight of 600 kN and A=0.3. Calculate their base shears and discuss which building is under more lateral force and why.
Show hintHide hint
Apply the formula correctly for both buildings and compare results.
Question 6.
If a hospital has a seismic weight of 1000 kN and is located in a very high seismic zone (zone V) where A is estimated to be 0.36, calculate the base shear and discuss its implications for the design.
Show hintHide hint
Remember to consider the implications for safety and the need for appropriate design measures.
