Challenge Problems
Push your limits with advanced challenges
Design a tall building (10 stories) with a given mass distribution. Compare the forces experienced at the base using both inverted triangular and parabolic models.
💡 Hint: Use the total mass distribution of the building in your calculations.
Evaluate a scenario where a building's mass is higher on upper floors. Discuss how this might affect the choice of seismic force distribution and why.
💡 Hint: Think about how weight affects sway and stability during seismic events.
