WebEarthquake design spectraGiven a earthquake ground acceleration, there is no difficulty to computeresponse using Newmark’s method as the previous example. Therefore, we cangenerate a response spectrum for that earthquake. We are interested in the maximum relative displacement, velocity, andtotal accelerations. WebPreliminary spectral analyses of low-amplitude ambient vibration data and that from a small earthquake reveal specific response characteristics of this new bridge and the free-field in its proximity. There is coherent tower-cable-deck interaction that sometimes results in amplified ambient motions.
