What does the importance factor (I) modify in the seismic base shear calculation?
💡 Hint: Consider which buildings need more robustness.
True or False: The response reduction factor R is applied because materials behave the same way under all conditions.

Challenge Problems
Push your limits with advanced challenges
A building designed for an Importance Factor of 1.5 in a zone with Z = 0.36 experiences a spectral acceleration S_a/g of 0.4g. If the total seismic weight is 800 kN, calculate the design base shear V_b.
💡 Hint: Insert the values carefully following the formula.
Discuss what would happen if the seismic weight is underestimated in a tall building located in the highest seismic zone.
💡 Hint: Consider the relationship between weight and structural stability.
