Challenge Problems
Push your limits with advanced challenges
Given a building with a natural frequency of 2 Hz, determine the risks if predominant ground motion has a frequency of 2.2 Hz during an earthquake.
💡 Hint: Assess the proximity of the frequencies to understand the resonance impact.
Calculate the potential inertia force experienced by a mass of 500kg with a Peak Ground Acceleration of 0.8g during an earthquake.
💡 Hint: Remember the formula for force: F = ma.
