Challenge Problems
Push your limits with advanced challenges
You are designing a new school building in a Zone III area with a seismic weight of 2000 kN. Given the importance factor is 1.0, the response reduction factor is 4, and Sa/g = 1.5, calculate the base shear.
💡 Hint: Use the provided values and the base shear formula carefully.
If a hospital with an importance factor of 1.5 and a seismic weight of 2500 kN is in Zone V, how will you calculate the base shear if Sa/g is 1.8 and R is 5?
💡 Hint: Substitute the values into the formula step by step for accuracy.
