Challenge Problems
Push your limits with advanced challenges
Consider a structure in Zone III with a Z value of 0.20, Importance Factor of 1.25, Response Reduction Factor of 4, and a Spectral Coefficient of 1.2. Calculate Ah and discuss the implications of these values for structural design.
💡 Hint: Focus on plugging in values carefully into the formula.
Analyze a building designed with higher ductility (R=5) in a high seismic zone (Z=0.36) but with a lower importance factor of 1.0. What structural advantages does a higher R provide?
💡 Hint: Consider how ductility plays a role in earthquake resistance.
