MAXIMA EARTHQUAKES FOR SEISMIC DESIGN OF STRUCTURES
A use of optimal design was done to determine the level of security that has to be yielded in the new version on the Seismic Design Chapter of the Mexican Handbook of Civil Constructions. The test of the optimization was done for essentially short-period conventional building structures (called typical of the Group B or TGB).Optimal design coefficients, as well as the correspondent return periods, were obtained for the whole Mexican territory. It was found that in low seismicity zones, these coefficients can be associated to very long return periods, with low probabilities of occurrence. Maxima earthquakes were invoked in order to examine the intensities. Both probabilistic and deterministic maxima earthquakes were useful to identify the maxima intensities that is possible to obtain in a classical hazard approach. Attenuation laws with truncated distribution were used to account for the physical inherent saturation.
