Chapter 6.P1, Problem 3P

A majority of the buildings that collapsed during theMexico City earthquake of September $19,1985$, were around $20$ stories tall. The predominant period of the earthquake ground motion, around $2.0$ s, was close to the natural period of vibration of these buildings. Other buildings, of differentheights and with different vibrational characteristics, wereoften found undamaged even though they were located rightnext to the damaged $20$-story buildings. Explain whether themodel described in this project provides a possible explanation for these observations. Your argument should be supported by computer simulations and graphs.
