5. During the Mexico City earthquake of 1985 certain buildings collapsed, while others remained standing. What was the issue with the buildings that collapsed? How could these collapses have been avoided? 6. What are some other examples of resonance? How does resonance affect these different systems? 7. Structural engineers consult with geologists to help predict the expected frequency of earthquake motions at a given site. They use this information to then make sure that buildings on that site do not have the same natural frequency as the expected earthquake input motions to avoid setting up resonance, in which the displacements of the building are amplified. What are some different strategies you might use to change the frequency of a building? Is it better to design buildings that are stiffer or more flexible?
