A long‐span suspension bridge is going to be built in an active seismic region in Japan. The structural earthquake engineer can choose the design ground‐motion parameter with respect to three return periods: 475, 950 and 2500 years. Which is the most suitable return period to select and why? What is the associated probability of the peak ground acceleration for the return period being exceeded?
