What is the primary goal of response spectrum analysis?
💡 Hint: Think about why engineers need to prepare for earthquakes.
True or False: Higher modes are always significant in seismic design for low-rise buildings.
💡 Hint: Consider how the number of stories might affect mode significance.

Challenge Problems
Push your limits with advanced challenges
A multi-storey building has a response dominated by its first two modes. If the first mode has a frequency of 2 Hz and the second mode has a frequency of 3 Hz, calculate the expected maximum displacements if the building is subjected to seismic loading of 0.5g.
💡 Hint: Consider how you might convert frequency to displacement using response spectra.
Critically evaluate what might happen if a designer decides to ignore higher mode effects in a 50-story building located in a seismic-prone area.
💡 Hint: Think about how modes interact and how neglecting them could lead to unexpected structural behavior.
