Site response in a representative region of Manzanillo, Colima, Mexico, and a comparison between spectra from real records and spectra from normative

For the majority of the cases we observe a reasonable agreement between the values of the dominant periods computed according to the MOC-CFE [2] normative and those obtained directly from Transfer Function (TF). On the other hand, we found significant differences between design spectra and response spectra obtained from seismic records for the 0.1-0.6 s interval. Amplitudes are underestimated for the first ones.
