A structure undergoes a forced vibration due to seismic activity. If the first three modal frequencies are 1.0 Hz, 1.5 Hz, and 2.0 Hz, how would you determine the significant modes necessary for a seismic response analysis?
💡 Hint: Consider the significance of the first modes and how they relate to the overall response.
Discuss how neglecting higher modes might affect a tall building's displacement during an earthquake. What additional factors should engineers consider?
💡 Hint: Reflect on the structural characteristics of tall buildings and the role of dynamic factors.
