Challenge Problems
Push your limits with advanced challenges
Consider a structure that has an Importance Factor of 1.2 and a Response Reduction Factor of 4. If the spectral acceleration Sa is 0.5 m/s² and the weight of the building is 1500 kg, calculate the design base shear.
💡 Hint: Remember to break down the formula and replace variables step by step.
Discuss the implications of having a lower Importance Factor and higher Response Reduction Factor. How would that impact the safety and functionality of a structure?
💡 Hint: Think about real-world scenarios where buildings serve critical versus non-critical roles.
